1. SE, standard error; CI, confidence interval, PC, principal component; DFM, decreased fetal movement.
2. aOutcome (binary dependent) variable = pathology identified at consultation (22/148 events). Analysis included fitting a mixed-effects model to account for multiple consultations within pregnancies. Women in the sample had one (n=127), two (n=9), or three (n=1) DFM-related consultations. Mean gestational age at time of consultation was 250 days (range, 184-292 days; standard deviation, 31 days).
3. bOutcome (binary dependent) variable = fetal compromise at time of consultation (27/76 events). No women attended more than one consultation within 21 days before birth. Mean gestational age at time of consultation was 271 days (range, 213-292; standard deviation, 16 days).
