SMG, Solar Market Garden; WG, women’s group; NWG, non-women’s group; did, difference-in-differences; see, standard error of the estimate; HDDS, Household Dietary Diversity Score; n, total number of women involved in the analysis; WDDS-10, Women’s Dietary Diversity Score (ten food groups).
P < 0·01 for DID estimate.
DID impact estimates between comparison and intervention groups controlled for age, household size, latrines, electricity connection, health-care insecurity, socio-economic status and type of group. ‡Within SMG villages = SMG WG v. SMG NWG.
Within WG = SMG WG v. comparison WG.
