SMG, Solar Market Garden; WG, women’s group; NWG, non-women’s group; DID, difference-in-differences; see, standard error of the estimate; n, total number of women involved in the analysis.
P < 0·05, ***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.
