¹Values are mean ± SD or, for sex, percentage, with comparisons between the IFA and MM groups assessed by regression, with intervention as the independent variable and with robust SEs to account for cluster randomization; missing observations: n = 2 for gestational age and first and late pregnancy assessments; n = 8 for gestational age at birth; n = 2 for birth weight; n = 5 for birth length; n = 41 for weight-for-length z score. IFA, iron folic acid; MM, multiple micronutrient.

²BMI reported in early pregnancy (enrollment), in the absence of prepregnancy BMI. IFA, iron folic acid; MM, multiple micronutrients.
