Hazard ratios (HRs) for different health outcomes according to types of maternal diabetes.

aModel 1: Hazard ratios (HRs) were adjusted for maternal age (<20, 20–24, 25–29, 30–34, 35–39, and 40+), parity (1, 2, and 3+), sex (boy and girl), maternal education (low, middle, and high), maternal marital status (yes or no), calendar year (1977–1981, 1982–1986, 1987–1990, 1991–1993, 1994–1998, 1999–2003, and 2004–2008).
bModel 2: HRs after exclusion of children with congenital malformations and after adjustments for the same variables as that in model 1.
cModel 3: HRs after exclusion o children with congenital malformations and after extended adjustments in the Model 1 by including gestational age at birth as a continuous variable, birth weight, and square of the birth weight.
