¹H is a measure of the extent of heterogeneity, a value of H = 1 indicates homogeneity of effects and a value of H > 1 indicates a potential heterogeneity of effects.

²I² describes the proportion of total variation in study estimates that is due to heterogeneity, a value > 50% indicates presence of heterogeneity.

CI: Confidence interval; N: Number; 95%CI: 95% Confidence interval; NA: Not available; HCWs: Healthcare workers.
