↵a k = number of subject groups;
↵b QM = heterogeneity statistic (Cochran's Q) – tests whether any coefficient (not including the intercept) is significantly different than 0;
↵c I2 = % of total variability due to heterogeneity;
↵d R2 = % of total heterogeneity explained by the covariate(s);
↵* p-Value<0.0001; CI, confidence interval; —, value does not need to be determined.
