CAL = calprotectin; LAZ = length-for-age z-score; MPO = myeloperoxidase; NEO = neopterin; WLZ = weight-for-length z-score; MUAC = mid-upper arm circumference. Estimates are P-value for interaction. ANCOVA regression models adjusted for baseline value of outcome of interest, age at enrollment, and district of residence at enrollment were used to examine the effect modification. Bold indicates values are statistically significant or marginally significant P-values.
