Sensitivity analyses
At baseline, there were no significant differences in age (We identified two outlier observations with energy intakes above 16 736 kJ (4000 kcal) at the 6-month follow-up and performed the primary analysis with and without these outliers. Energy intake was not statistically different between control and intervention arms in analysis when outliers were included (9292·4 kJ Additionally, we conducted an analysis in which we included only those participants in the control arm who used their biomass-burning stoves for more than 50 % of their cooking time and participants in the intervention arm who used LPG stoves for more than 95 % of their cooking minutes. Differences in average energy intake between control and intervention participants (averaged across the 6- and 12-month visits) remained non-significant (9984·4 kJ
