Difference in standardised cognitive function by 10 years greater reproductive and chronological age. a Main analyses including all women with at least one measure of cognitive function (N = 2402–2408). b Sensitivity analyses restricted to women with measures of cognitive function at all three time points (N = 1385–1386). Note: Reproductive age is measured as years since final menstrual period (FMP) and chronological age is centred at age 50 and in interaction with whether the observation is before and after FMP. Analyses adjusted for practice effects (baseline assuming no practice effects), fieldworker effects, education (baseline CSE/vocational/O-level) and age at first pregnancy (centred at 26)
