Changes in energy poverty and health outcomes between baseline and follow-up for the intervention and comparison groups; participants were weighted by stabilised inverse probability treatment weights (IPTW)

¹Var%, percentage of variation=[(%Post-%Pre) / %Pre]

²The McNemar test was used

IPTW (inverse probability treatment weights) were estimated by logistic regression adjusted by age, sex, place of birth, household composition educational level, employment status, face unexpected expenses above 750€ and tenure status
