Figure 3. Regression to the mean assessment: association between telomere length at Year 1 and change in telomere length between Years 1 and 2.

T/S ratio = unit for relative telomere length.

Figure 3—figure supplement 1. Regression to the mean comparison of unadjusted association between change in telomere length and growth.

Figure 3—figure supplement 1.

Unadjusted differences in mean anthropometry Z score between 10th and 90th percentile of change in telomere length between Years 1 and 2. Unadjusted associations corrected for the regression to the mean (RTM) effect using the equation in Verhulst et al., 2013. LAZ = length-for-age Z score; WAZ = weight-for-age Z score; WLZ = weight-for-length Z score; HCZ = head circumference-for-age Z score.

Figure 3—figure supplement 2.

Adjusted differences in mean anthropometry Z score between 10th and 90th percentile of change in telomere length between Years 1 and 2. Adjusted associations corrected for the regression to the mean (RTM) effect using the equation in Verhulst et al., 2013. LAZ = length-for-age Z score; WAZ = weight-for-age Z score; WLZ = weight-for-length Z score; HCZ = head circumference-for-age Z score. Adjusted for pre-specified covariates: Child age, child sex, birth order, prior child length and weight measurements from Year 1 (included in Year 2 outcomes only), season of measurement, time between anthropometry measurements (included in growth velocity and change in growth measurements between Year 1 and Year 2 outcomes only), caregiver-reported diarrhoea, mother’s age, mother’s height, mother’s education level, mother’s Center for Epidemiologic Studies Depression Scale Revised (CESD-R) score, mother’s Perceived Stress Scale score, mother’s lifetime exposure to physical, sexual, and emotional intimate partner violence, household food insecurity, number of children <18 years in the household, number of individuals living in the compound, distance in minutes to the primary water source, household floor materials, household wall materials, household electricity, and household assets (wardrobe, table, chair, clock, khat, chouki, radio, television, refrigerator, bicycle, motorcycle, sewing machine, mobile phone, cattle, goats, and chickens), and treatment arm (control or N + WSH) (Supplementary file 1a).
