Histograms of estimated FPC1 scores (solid bars in Panels a and b), original FPC2 scores (clear bars in Panels c and d) and adj-FPC2 scores (solid bars in Panels c and d) in boys and girls. The FPC1 scores for WHO “pseudo children” (growing along WHO percentiles) are shown as dashed lines in Panels a and b, whereas most study children were below the WHO 50th percentile. Positive adj-FPC2 scores in Panels c and d quantified the degree of growth faltering. Abbreviations: adj-FPC2, adjusted FPC2; FPC, functional principal component; WHO, World Health Organization
