*In the 1946-51cohort, this category reflects women with no formal qualifications.
†Where stroke was self-reported, the mental health score from that same survey was used; for hospital-recorded strokes where stroke was not self-reported, the mental health score from the survey subsequent to the admission was used; where there was neither hospital-recorded nor self-reported stroke, the first available mental health score from the included surveys was used.
