REGRESSION
We successfully reenrolled 979 children at the home visit and collected data from 966 children at the project office visit, representing 107% of our target sample size (900), 73.2% of the 1320 pregnant women enrolled in the parent trial, and 79.4% of the 1217 children eligible for re-enrolment (excluding those known not to have survived). We successfully completed teacher interviews at school visits for 906 children. The proportion lost to follow-up was balanced between the intervention groups (Trial profile. IFA, iron and folic acid; MMN, multiple micronutrient; SQ-LNS, small-quantity lipid-based nutrient supplement.The 966 included in the analysis were similar to the 354 enrolled in the parent trial but lost to follow-up regarding most background characteristics, such as baseline maternal age, education, and BMI (Among those included in the analysis, background characteristics were similar in the SQ-LNS and control groups (Group characteristic comparisons.EC-HOME, Early Childhood Home Observation for the Measurement of the Environment Inventory; MC-HOME, Middle Childhood Home Observation for the Measurement of the Environment Inventory; SQ-LNS small-quantity lipid-based nutrient supplement.Values are given as mean (SD) or % [Estimated prepregnancy BMI was calculated from estimated prepregnancy weight (based on polynomial regression with gestational age, gestational age squared, and gestational age cubed as predictors) [Proxy indicator for household socioeconomic status constructed for each household based on ownership of a set of assets (e.g., radio and television), lighting source, drinking water supply, sanitation facilities, and flooring materials. Household ownership of this set of assets is combined into an index (with a mean of zero and standard deviation of one) using the principal components analysis. A higher value represents a higher socioeconomic status.
