RR = relative risk.

^*Wald test for an ordinal variable representing the median for each quartile of adherence, introduced into the model as a continuous predictor.

^†From generalized estimating equations with the Poisson distribution. IgG seroconversion was the dichotomous outcome, and predictors included indicator variables for quartiles of adherence to each pattern plus child’s sex, age, height-for-age z-score, maternal education (one indicator for primary), home ownership, housing type, number of people per room, and household socioeconomic status. Robust estimates of the variance were specified in all models.
