- OR odds ratio, CI confidence interval, K number of studies combined
- aRandom-effects model was used when the P for heterogeneity test < 0.05; otherwise, the fixed-effect model was used
- bP < 0.05 is considered statistically significant for Q statistics
- cEgger’s test to evaluate publication bias, P < 0.05 is considered statistically significant
