^{a}k = number of subject groups;↵

^{b}Q_{M}= heterogeneity statistic (Cochran's Q) – tests whether any coefficient (not including the intercept) is significantly different than 0;↵

^{c}I^{2}= % of total variability due to heterogeneity;↵

^{d}R^{2}= % of total heterogeneity explained by the covariate(s);↵* p-Value<0.0001; CI, confidence interval; —, value does not need to be determined.
