Abstract Our study investigates the interlink between liquidity, corporate governance and firm value with the adoption of meta-analysis. The final sample consists of 428 studies extracted from 55 papers, covering 632,196 firm-year observations in a worldwide scope. The diversity in data is believed to reduce possible homogeneity due to regional or time period concentration. Using random-effects model, it is reported that both illiquidity factors (Spread and Amihud illiquidity) can significantly worsen the performance of a firm, while the corporate governance – firm value connection is significantly positive via three out of four factors (Corporate governance index, Board size and Institutional ownership). Besides studying the overall relationship direction, the paper also looks into its heterogeneity. The existence of heterogeneity is confirmed in all liquidity – firm value and governance – firm value relationship. The running of meta-regression indicates that both illiquidity factors are significantly moderated by most of the examined paper characteristics, whilst only two out of four corporate governance indicators (Corporate governance index and Institutional ownership) are significantly altered.

Background Breast engorgement and breast pain are the most common reasons for the early cessation of exclusive breastfeeding by mothers. Research Aims (1) To examine the influence of breastfeeding educational interventions on breast engorgement, breast pain, and exclusive breastfeeding; and (2) to identify effective components for implementing breastfeeding programs. Methods Randomized controlled trials of breastfeeding educational interventions were searched using five English and five Chinese databases. Eligible studies were independently evaluated for methodological quality, and data were extracted by two investigators. In total, 22 trials were identified, and 3,681 participants were included. A random-effects model was used to pool the results, and a subgroup analysis and meta-regression analysis were conducted. Results Breastfeeding education had a significant influence on reducing breast engorgement at postpartum 3 days (odds ratio [OR]: 0.27, 95% CI [0.15, 0.48] p < .001), 4 days (OR: 0.16, 95% CI [0.11, 0.22], p < .001), and 5–7 days (OR: 0.24, 95% CI [0.08, 0.74], p = .013) and breast pain (standardized mean difference: −1.33, 95% CI [−2.26, −0.40]) at postpartum 4–14 days. Participants who received interventions had higher odds of exclusive breastfeeding. Breastfeeding educational interventions provided through lecture combined with skills practical effectively reduced breast engorgement (OR: 0.21; 95% CI [0.15, 0.28]; p = .001) and improved exclusive breastfeeding at postpartum 1–6 weeks (OR: 2.16; 95% CI [1.65, 2.83]; p = .001). Conclusions Breastfeeding educational interventions have been effective in reducing breast engorgement, breast pain, and improved exclusive breastfeeding. A combination of knowledge and skill-based education has been beneficial for sustaining exclusive breastfeeding by mothers.

Our meta-analysis aimed to evaluate the diagnostic performance of surveillance magnetic resonance imaging (sMRI) for detecting hepatocellular carcinoma (HCC), and to compare the diagnostic performance of sMRI between different protocols. Original articles about the diagnostic accuracy of sMRI for detecting HCC were found in major databases. The meta-analytic pooled sensitivity and specificity of sMRI for detecting HCC were determined using a bivariate random effects model. The pooled sensitivity and specificity of full MRI and abbreviated MRI protocols were compared using bivariate meta-regression. In the total seven included studies (1830 patients), the pooled sensitivity of sMRI for any-stage HCC and very early-stage HCC were 85% (95% confidence interval, 79–90%; I2 = 0%) and 77% (66–85%; I2 = 32%), respectively. The pooled specificity for any-stage HCC and very early-stage HCC were 94% (90–97%; I2 = 94%) and 94% (88–97%; I2 = 96%), respectively. The pooled sensitivity and specificity of abbreviated MRI protocols were 87% (80–94%) and 94% (90–98%), values that were comparable with those of full MRI protocols (84% [76–91%] and 94% [89–99%]; p = 0.83). In conclusion, sMRI had good sensitivity for detecting HCC, particularly very early-stage HCC. Abbreviated MRI protocols for HCC surveillance had comparable diagnostic performance to full MRI protocols.

Lately, the effect of quercetin supplementation (QS) on endurance performance (EP) and maximal oxygen consumption (VO2max) has been receiving much scientific and media attention. Therefore, a meta-analysis was performed to determine QS’s ergogenic value on these variables. Studies were located with database searches (PubMed and SPORTDiscus) and cross-referencing. Outcomes represent mean percentage changes in EP (measured via power output) and VO2max between QS and placebo. Random-effects model meta-regression, mixed-effects model analog to the ANOVA, random-effects weighted mean effect summary, and magnitudebased inferences analyses were used to delineate the effects of QS. Seven research articles (representing 288 subjects) were included, producing 4 VO2max and 10 EP effect estimates. Mean QS daily intake and duration were, respectively, 960 ± 127 mg and 26 ± 24 d for the EP outcome and 1,000 ± 0 mg and 8 ± 23 d for the VO2max outcome. EP was assessed during exercise with a mean duration of 79 ± 82 min. Overall, QS improved EP by 0.74% (95% CI: 0.10–1.39, p = .02) compared with placebo. However, only in untrained individuals (0.83% ± 0.78%, p = .02) did QS significantly improve EP (trained individuals: 0.09% ± 2.15%, p = .92). There was no relationship between QS duration and EP (p = .69). Overall, QS increased VO2max by 1.94% (95% CI: 0.30–3.59, p = .02). Magnitude-based inferences suggest that the effect of QS on EP and VO2max is likely to be trivial for both trained and untrained individuals. In conclusion, this meta-analysis indicates that QS is unlikely to prove ergogenic for aerobic-oriented exercises in trained and untrained individuals.

The Relationship

Corporate governance is, undoubtedly, extremely essential for the performance of the organizations. The structure of corporate ownership has significant impact on the external as well as internal performance factors of firms. The relationship between corporate governance indicators and firm performance has been extensively investigated; however, a little work has been done on how the structure of board can add value to the firm. This paper sheds light on the relationship of some aspects of board structure like board size, board composition, and CEO duality with the performance variables Tobin’s Q and Return on Assets (ROA) by using a sample of 53 firms of cement and sugar sectors of Pakistan for a period of 2005-2007. The results indicate that the firms perform better with moderate board size and the performance is adversely affected if CEO also acts as chairperson of board of directors whereas the external directors can play a positive role for firm performance in Pakistan.

Abstract Background . There is evidence that males have higher incidence rates (IR) of campylobacteriosis than femlaes. The objectives of this study were to determine whether the sex differences differ between age groups and are consistent over different countries and over different time periods. Methods. We obtained data on incidence rates of campylobacteriosis by sex and age group over a period of 11-26 years from seven countries. Male to female incidence rate ratios (IRR) were computed by age group, country and time period. For each age group, we used meta-analytic methods to combine the IRRs. Sensitivity analysis was used to test whether the results are robust to differences between countries and time periods. Meta-regression was conducted to estimate the different effects of age, country, and time period on the IRR. Results . In the age groups <1, 1-4, 5-9, 10-14, 15-44, 45-64 and 65+ years old, the pooled IRRs (with 95% CI) were 1.31 (1.26-1.37), 1.34 (1.31-1.37), 1.35 (1.32-1.38), 1.73 (1.68-1.79), 1.10 (1.08-1.12), 1.19(1.17-1.21) and 1.27 (1.24-1.30), respectively. For each age group, the excess campylobacteriosis incidence rates in males differed at different age groups. However, despite some quantitative differences between countries, the excess was consistently present over long time-periods. In meta-regression analysis, age group was responsible for almost all the variation in the IRRs. Conclusions . The male predominance in campylobacteriosis incidence rates starts in infancy. This suggests that this is due, at least in part, to physiological or genetic differences and not just behavioural factors. These findings can provide clues to the mechanisms of the infection and could lead to more targeted treatments and vaccine development.

The purpose of this study is to investigate corporate governance’s quality for Shareholding Companies Listed on the Amman Stock Exchange; to see how corporate governance index (CGI) and firm performance and firm value are associated; and last but not the least is to check how CGI affects firm performance and firm value. A comprehensive CGI containing 112 points was constructed and analyzed for years 2010 and 2015. It reported that the Jordanian industrial and service companies have a good CGI during these two years. Pearson correlation has showed positive but weak relationships between CGI and all variables in the two years. Multiple regression analysis was performed to evaluate corporate governance index effects on the performance and the value of firm. The results did not support the hypotheses that CGI significantly affects these two variables. To reach to better corporate governance in Jordanian industrial and service companies, the Jordanian authorities might need to modify the inconsistence between laws and corporate governance rules.
