Ref: reference group; N: number; het: heterogeneity; OR: Odds ratio; CI: confidence interval 1: Adjusted for age (<50, 50–59, 60–69, 70+) and sex 2: Further adjusted for family size (using the total number of children and siblings; categories: <6; 6 or more; missing). 3: Further adjusted for number of siblings (categories: <2; 3 or more; missing) 4: Further adjusted for number of children (0/2; 3or more; missing) 5: Adjusted for age (<70, 70+) and sex, Ncontrols = 189; Ncases = 59 P-values were calculated using Wald-test. Black squares indicate OR, the area of each square being proportional to the amount of statistical information contributed. Horizontal lines represent 95% CI.
