Note: Missing observations on exposure, outcome, and covariates overlap. The total excluded missing obs is the union of the three sets (not the sum). Missing observations refers to cases where data were not recorded for an item. Exposure refers to a measure of energy poverty. Outcome refers to a measure of health. Covariates are the variables used to adjust the analyses for confounding.
