* Univariate and multivariate logistic regression showing crude (unadjusted) and adjusted odds ratios (OR) with their 95% confidence intervals (CI). † OR adjusted for maternal weight, age, parity, smoking habits and ethnicity (considered as potential confounding factors). DFM: cases of decreased fetal movements.
