Time series regression models were constructed to analyze the contributions of various factors (including treatment allocation) to time trends in the dependent variables shown. Final regression models are shown for each dependent variable, and treatment allocation is included even when not significant because this was the primary hypothesis being examined. MM, multiple micronutrient.
