Background: Censoring due to early drug discontinuation (EDD) or withdrawal of consent or loss to follow-up (WCLFU) can result in postrandomization bias. In oncology, censoring rules vary with no defined standards. In this study, we sought to describe the planned handling and transparency of censoring data in oncology trials supporting FDA approval and to compare EDD and WCLFU in experimental and control arms. Methods: We searched FDA archives to identify solid tumor drug approvals and their associated trials between 2015 and 2019, and extracted the planned handling and reporting of censored data. We compared the proportion of WCLFU and EDD between the experimental and control arms by using generalized estimating equations, and performed logistic regression to identify trial characteristics associated with WCLFU occurring more frequently in the control group. Results: Censoring rules were defined adequately in 48 (59%) of 81 included studies. Only 14 (17%) reported proportions of censored participants clearly. The proportion of WCLFU was higher in the control group than in the experimental group (mean, 3.9% vs 2.5%; β-coefficient, −2.2; 95% CI, −3.1 to −1.3; P<.001). EDD was numerically higher in the experimental arm in 61% of studies, but there was no statistically significant difference in the proportion of EDD between the experimental and control groups (mean, 21.6% vs 19.9%, respectively; β-coefficient, 0.27; 95% CI, −0.32 to 0.87; P=.37). The proportion of EDD due to adverse effects (AEs) was higher in the experimental group (mean, 13.2% vs 8.5%; β-coefficient, 1.5; 95% CI, 0.57–2.45; P=.002). WCLFU was higher in the control group in studies with an active control group (odds ratio [OR], 10.1; P<.001) and in open label studies (OR, 3.00; P=.08). Conclusions: There are significant differences in WCLFU and EDD for AEs between the experimental and control arms in oncology trials. This may introduce postrandomization bias. Trials should improve the reporting and handling of censored data so that clinicians and patients are fully informed regarding the expected benefits of a treatment.

This study examines how piano-accompanied solfège reading practices of preservice music teachers ( N = 28) affect their performance on their musical hearing, reading, and writing (MHRW) classes. A pretest–posttest design with control groups was employed. The data were analyzed by 2 × 2 split-plot analysis of variance (ANOVA) and one-way ANOVA. Consequently, a significant difference was not found between the MHRW performance scores of the experimental and control groups. An analysis of mean performance scores revealed that the scores received by the control group were higher than those of the experimental group after the practice. Follow-up interviews that were held with 14 students after the experimental implementation revealed that students believed piano-accompanied courses were more useful, and they felt more comfortable with piano accompaniment. Although MHRW performance scores indicated that piano-accompanied solfège reading practices did not have a significant effect on preservice music teachers’ MHRW performances, it helped them participate in courses more enthusiastically.

Aims: Most people in the community believe that substance abuse is masculine, while women are progressing alongside men in this area, with statistics indicating an increasing number of infected women. The purpose of this study was to determine the effectiveness of enriching couples relationships on tolerance of distressed women who were drug abusers Methods & Materials: This is a quasi-experimental study with pre-test, post-test and follow-up test with control group. Initially, 40 women were selected from the study and 20 were randomly assigned to the experimental group and 20 to the control group. Subjects were then assessed using a distress tolerance test (Simmons & Gahr, 2005). Experimental group participants participated in enrichment sessions based on Doba, Graham, Britz and Minatra (2009) choice theory and control group subjects remained on the waiting list. A follow-up test was taken after three months. Multivariate analysis of variance with repeated measures was used to analyze the data. The above analyzes were performed with SPSS V. 24 software Findings: The results indicated that there was a significant difference between the mean of pre-test, posttest and follow-up scores of distress tolerance scales in the experimental and control groups. (P<0.05). The mean distress tolerance in the experimental group increased from 34.533 to 42.80 in the pre-test phase and reached 42.533 in the follow-up phase. Also, the significant interaction between the stages with the experimental group in the mentioned variable indicates that in the post-test and follow-up stages, the mean of the experimental groups was significantly higher than the control group. Conclusion: Due to the increasing trend of addiction in women, proper education is one of the essentials. Therefore, it is recommended to take effective steps to improve couple distress tolerance training by enriching couple relationships

Objective: To compare the effects of the use and non-use of a disinfectant on the outcomes of separation of the labia minora in infants. Methods: The patients were randomly divided into an experimental group with 24 cases and a control group with 25 cases. In the control group, 1% iodophor was used to clean and disinfect the large and small labia and the surrounding skin, while normal saline was used in the experimental group. Other procedures such as the surgery and nursing method were the same in both groups. Results: There were no symptoms of urinary tract infection such as redness of the vulva, swelling, pain, and abnormal urination in the test group and control group after three days of follow-up, and no recurrence was seen at one month of follow-up. There was no statistically significant difference between the two groups (P > 0.05). Conclusion: Use or non-use of a disinfectant to clean the urethral opening before separation of the labia minora has no significant effect on the outcomes, and does not cause postoperative urinary tract infection symptoms. Moreover, non-use of a disinfectant can prevent local irritation and reduce the economic burden on the patients.

Objective: India is the second country after China having the highest population prevalence of diabetes. Several research studies investigating diabetes have been done, but not much work has been done on prediabetes. The purpose of this study was to investigate the effect of nutrition and lifestyle modification on prediabetic females. Methods: A total of 120 prediabetic females from Ludhiana city were divided into 2 matched groups: control group (n = 60) and experimental group (n = 60). Impact of nutrition intervention for dietary and lifestyle modification (for 3 months) was assessed on the anthropometric, dietary, biochemical parameters, and diabetes risk score of the experimental group and control group (no intervention). Results: All the selected 120 subjects completed the study (experimental group = 60; control group = 60). There was significant difference in the changes between the 2 groups throughout the study. The fasting blood glucose and glycated hemoglobin A1c levels of the experimental group subjects reduced significantly ( P ≤ .01). However, no change was observed among the control group subjects. The lipid profile of the experimental group showed a significant improvement ( P ≤ .01). Conclusion: Nutrition counselling of the prediabetics regarding dietary and lifestyle modification is recommended so as to improve their metabolic control, thus preventing them from being diabetics.

The study pertains to the parenting stress, which is believed to be the resultant of child disability and further assesses the needs of the families across selected pockets of Himachal Himalaya. Perceived Stress Questionnaire (PSQ) and Need Assessment Scale were used for the purpose. For assessing the stress level among the parents, PQS was administered among two hundred parents having disabled children, herein called experimental group and two hundred parents with normal children, herein called control group. A three point Need assessment scale was used to measure the needs of 200 families on five different parameters. The result of t-test shows the significant difference between experimental and control groups indicating that the parents of disabled children experience more stress than their control counterpart. The study indicates that people need proper guidance and information regarding a child’s disability, nutritional requirements of a child, vocational training and child management. There is a need for proper counselling for parents suffering from stress and creating consciousness among parents of children with disabilities and in the society.

       The present study aims at investigating the effect of applying group work technique on developing non-English major students' attitude towards learning English as a foreign language .Two null hypotheses have been formulated; the first hypothesis states that there is no statistically significant difference between the experimental and control group in their attitude towards learning EFL after the experiment. The second one states that there is no statistically significant difference in (pre-post questionnaire) of the experimental group students' attitude towards learning EFL. To achieve the aim of the study, and verify its hypothesis, the researcher has applied eight week experiment. A sample of 62 students has been chosen and divided into experimental and control groups. It has been chosen randomly from the second year students in the Basic Education College/ Department of History/Academic year (2017-2018).        The attitude questionnaire for both groups was applied before and after the experiment. After processing the results statistically, it was found that there is a statistically significant difference in favor of the experimental group. Having used the t-test formula, it was found that there is statistically significant development in the experimental group students' attitude towards learning EFL, which in turn indicates that the use of GWT is more effective than the traditional method.  Conclusion and recommendations were drawn.
