    Abstract: Mass vaccination initiatives are underway worldwide, and a considerable percentage of the world’s population is now vaccinated. This study examined the association of COVID-19 deaths per 1000 cases with a fully vaccinated population. The global median deaths per 1000 cases were 15.68 (IQR 9.84, 25.87) after 6 months of vaccinations and 11.96 (IQR 6.08, 20.63) after 12 months. Across 164 countries, we found significant variations in vaccination levels of populations, booster doses, and mortality, with higher vaccine coverage and lower mortality in high-income countries. Several regression models were performed to test the association between vaccination and COVID-19 mortality. Control variables were used to account for confounding variables. A 10-percentage-point increase in vaccination was associated with an 18.1% decrease in mortality after 6 months (95%CI, 7.4–28.8%) and a 16.8% decrease after 12 months (95%CI, 6.9–26.7%). A 10-percentage-point increase in booster vaccination rates was associated with a 33.1% decrease in COVID-19 mortality (95%CI, 16.0–50.2%). This relationship is present in most analyses by country income groups with variations in the effect size. Efforts are needed to reduce vaccine hesitancy while ensuring suitable infrastructure and supply to enable all countries to increase their vaccination rates.

    Abstract: To assess the association of the gender of the delivering physician and the odds of performing cesarean delivery. DATA SOURCES: CINAHL, ClinicalTrials.gov, Cochrane Library, PubMed, Scopus and Web of Science from the first year of records through May 2020. METHODS OF STUDY SELECTION: We included studies that reported odds ratios (OR), or data allowing the calculation of ORs, for cesarean delivery performed by female and male delivering physicians. We also included studies that reported the preference of physicians for performing cesarean deliveries. TABULATION, INTEGRATION, AND RESULTS: Independent data extraction was carried out by at least two researchers. Standard inverse-variance random effects meta-analysis was used to generate overall ORs. Finally, in two separate meta-analyses, we analyzed 15 studies containing clinical data for 1,269,625 births, and 11 studies containing data for the preference for delivery mode of 4,911 obstetricians. Both the crude and adjusted odds of a cesarean delivery were lower for those performed by female physicians (crude OR 0.75, 95% CI 0.68–0.84, τ 2 =0.029, adjusted OR 0.74, 95% CI 0.65–0.85, τ 2 =0.031). We also found that female physicians had a lower preference for cesarean delivery in both crude and adjusted analysis (crude OR 0.59, 95% CI 0.36–0.96, I 2 =77%, adjusted OR 0.58, 95% CI 0.40–0.84, I 2 =67%). CONCLUSION: Female physicians are less likely to perform cesarean delivery and less likely to prefer it. This was observed across different health systems and populations.
