 Childhood vegetable and fish intake and stroke mortality in the Boyd Orr survey of diet and health in pre-second world war Britain (1937 to 1939). *Adjusted for age, energy, and sex; †also adjusted for childhood family food expenditure, father’s social class, district of residence as a child, period of birth, season when studied as a child, and Townsend score for current address or place of death; ‡p value for linear test for trend, obtained by entering the quartiles as continuous terms. All models control for within-family clustering of diet by using the cluster option in Stata. Rate ratio and CI were calculated using Poisson regression.
