Odds ratios (and 95% confidence intervals) for ventriculomegaly (A.) and hypoechoic lesion (B.) calculated with logistic regression models. The three risk groups ISSI (intermittent or sustained systemic inflammation) without HTT, HTT (relative hyperthyrotropinemia) without ISSI, and both ISSI and HTT are each compared to the referent group that consists of newborns with neither ISSI nor HTT. All logistic regression equations also included a variable for gestational age.
