Note. OR = odds ratio; CI = confidence interval.

^aAdjusted for maternal age, occupation, and geographic origin. Fractional polynomials were used to adjust for maternal age.

^bP < .001 (Wald test of significance) for prenatal diagnosis; P = .54 (Wald test of significance) for continuation of pregnancy.

^cArtisan, small business owner, shopkeeper, shop assistant, service worker, skilled worker, or unskilled worker.
