Variable	Personal Variance Explained (%)	Kitchen Variance Explained (%)
Stove type	9.7	14.4
Electricity	1.8	0.6
Income	0.1	0.1
Measured stove use >28° C	0.7	0.1

Total Model
Predictors alone	18.9	22.2
Predictors and random effects	36.8	47.0

Note. Total model predictors alone represent the variance explained by fixed effects (marginal R²). Predictors and random effects are the variance explained by the entire model, including both fixed and random effects (conditional R²).
