  1. BW birthweight, CI confidence interval, FHR foetal heart rate, min. minutes, OR odds ratio
  2. aDifference between intra-hospital stillbirths and controls: OR 0.41, 95 % CI 0.21–0.81
  3. bIt was possible to calculate average time from last FHR till delivery in 63 (86 %) cases and 176 (86 %) controls. The interquartile ranges were 75–315 min. and 63–238 min., respectively
  4. cFor each one-hour increase in duration from last FHR assessment, the odds of stillbirth increased 20 % (OR 1.20; 95 % CI 1.08–1.34)
