IntroductionDespite the consistent evidence of the benefits of physical activity on preventing atherosclerotic cardiovascular diseases (ASCVD) and some cardiovascular risk factors, such as hypertension and dyslipidaemia, the prescription of drugs remains the most widely used approach to prevent ASCVD in clinical settings. The purpose of this study protocol is to provide a meta-synthesis methodology for comparing the effect of fixed-dose combination therapy and physical exercise on controlling cardiovascular risk factors and preventing ASCVD.Methods and analysisThis protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols and the recommendations of the Cochrane Collaboration Handbook. We plan to conduct a computerised search in Medline, Web of Science, Embase, Cochrane Database of Systematic Reviews and SPORTDiscus from inception to May 2020 for studies testing the effectiveness of physical exercise or fixed-dose combination drug therapy in preventing ASCVD, all-cause and cardiovascular mortality and controlling some cardiovascular risk factors (hypertension and dyslipidaemia). Since performing network meta-analyses (NMA) is a statistical approach that allows direct and indirect comparisons of interventions, where sufficient studies are included, we plan to perform the following NMA comparing the effect of fixed-dose combination therapy and physical exercise interventions on (1) improving lipid profile, (2) reducing blood pressure, (3) preventing cardiovascular events and all-cause and cardiovascular mortality and (4) improving compliance with the therapeutic strategy and reducing adverse events.Ethics and disseminationEthical approval will not be needed because data included in the NMA will be extracted from published trials that meet accepted ethical standards. The results will be published in academic peer-reviewed journals, and the evidence gathered by this project could be included in the preventive cardiovascular disease guidelines.PROSPERO registration numberCRD42019122794.

ABSTRACT Introduction To assess the effectiveness and safety of fixed dose combination (FDC) of antioxidants in treatment of idiopathic oligoasthenozoospermia. Materials and methods Placebo-controlled, Double-blind, randomized, Parallel three arm, Multicentric trial. Setting Fertility clinics of five centers across India. Patients One hundred and thirty-eight male subjects, aged between 21 and 50 years and subfertile for 1 year or more with the following baseline sperm selection criteria: Concentration <15 million/ml and total sperm motility <40%. Intervention(s) Eligible subjects were randomized to either of the three arms in a double-blind manner, i.e. arm 1 was given 2 tablets twice daily of FDC of antioxidants (coenzyme-Q10: 50 mg, L-carnitine: 500 mg, lycopene: 2.5 mg and zinc: 12.5 mg); arm 2 was given 1 tablet of FDC of antioxidants and one tablet of placebo twice daily and arm 3 was two tablets twice daily of matching placebo all for 180 days. Main outcome measure(s) The primary outcome measures were improvement in sperm count and sperm motility, whereas pregnancy rate was the secondary efficacy outcome. Results Compared to placebo, a statistically significant improvement was seen in sperm count (14.8-26.35 in arm 1 and 14.37-24.8 million/ml in arm 2, p < 0.0001), and sperm total motility (39.2-51.6% in arm 1 and 38.4-50.1% in arm 2, p < 0.0001), at 90 days, and treatment further improved these parameters at day 180. No intergroup difference was seen between arm 1 and arm 2. Mild adverse event of upper gastrointestinal discomfort by 8 subjects (three in arm 1; one in arm 2 and four subjects in arm 3) were reported. No serious adverse event was seen in the study. Conclusion Exogenous administration of fixed dose combination of antioxidants is a safe and effective therapy in improving the male subfertility.
