  1. SMD = standardized mean difference; 95% CI = 95% confidence interval; NE = SMD not estimable; S = reported differences between groups were significant; NS = reported differences between groups were not significant; NR = outcome measure not reported.
  2. * A negative SMD with 95% CI indicates a decrease in operative time, intraoperative blood loss and length of stay in favor of the study group.
