Association between serum AFB1‐lysine adduct level and height (left) or height‐for‐age difference (HAD, right) at the 4‐ and 10‐month follow‐up. Regression coefficients and 95% CIs (adjusted for clustering at the locality level using the Huber–White sandwich estimator) from the longitudinal mixed model are shown. Models controlled for child sex and age (squared), whether the child was born prematurely, child height (or HAD) at enrolment, child dietary diversity, maternal education, whether the mother was single, household size (i.e., number of individuals) at enrolment, home and asset ownership at enrolment, supplementation trial arm, and the follow‐up survey date. The models were estimated using actual serum AFB1‐lysine adduct level, log‐transformed serum adduct level (dropping two observations with unobservable [zero] serum AFB1‐lysine adduct level), and actual serum AFB1‐lysine adduct level without 4 outliers (observations above the 99th percentile, i.e., 4.10 pg/mg albumin). The number of observations ranged from 651 to 644
