†
Intervention effect is the OR for the association between home visit and coverage at midline or endline, divided by the OR for the association between home visit and coverage at baseline; this measure – which is not a true OR, rather a ‘ratio of ORs’ – estimates the association at midline or endline relative to (or ‘adjusted for’) that at baseline.
