Legend: Countries are the units of analysis. Green cells stand for correlations greater than 0.85. WMDOM: weighted mean difference from overall mean (absolute); WMROM: weighted mean ratio to overall mean (relative); UMDOM: unweighted mean difference from overall mean (absolute); UMROM: unweighted mean ratio to overall mean (relative); HLD: high-low difference among the best- and worst-performing groups (absolute); HLR: high-low ratio among the best- and worst-performing groups (relative).
