Figure 2. Weight-for-age growth curves of study children (as modeled by multiple linear regression) and reference populations in Uganda (11). Curves represent the median weight-for-age, averaged between boys and girls and controlling for concurrent Cryptosporidium spp. infection. The difference, 95% confidence interval, and significance of the interaction term between Enterocytozoon bieneusi and age reflect the difference in growth rates of children with and without microsporidiosis in ln(kg)/ln(age). R2 = 0.42, difference = –0.133, 95% confidence interval –0.23 to –0.03, p = 0.009.
