CMC Chronic medical condition (positive scores mean high variability in diagnosis). Cancer study type is coded as non-cancer studies (1) and cancer studies (2), meaning that negative beta coefficients indicate smaller effects for cancer studies. k = number of studies; d = Cohen’s d (effect size); Qb = Q statistic between studies (index of variability between the group means); Qw = statistic within studies (index of variability within the groups)
