Proportion of labouring women reaching each of six criteria for minimal acceptable routine surveillance during labour. Significant differences were found in FHR (OR 0.41, 95 % CI 0.21–0.81), cervical dilatation (OR 0.37, 95 % CI 0.21–0.68), and contractions (OR 0.26, 95 % CI 0.14–0.47). Intra-hospital stillbirths: documented positive FHR on admission, birthweight ≥2000 g. Controls: Apgar score ≥7, birthweight ≥2000 g. * Of all women at the hospital during active first stage of labour (n = 69 and n = 207, respectively). ** Of women with at least one FHR reading (n = 72 and n = 204, respectively). *** Of women reaching active phase of labour (n = 70 and n = 235, respectively). **** Of all women in the study (n = 72 and n = 249, respectively). FHR, foetal heart rate; BP, blood pressure; Temp, temperature
