Area under curve for satisfaction with pain relief and pain scores during active labour and after start pain relief in pregnant women allocated to patient controlled remifentanil or epidural analgesia in labour
| Measure (No of women per group) | Mean area under curve | ||
|---|---|---|---|
| Remifentanil | Epidural analgesia | Difference (95% CI) | |

| Satisfaction with pain relief after pain relief (447/347*) | 25.6 | 36.1 | −10.4 (−13.9 to −7.0) |
| Pain during active labour (687/671) | 30.9 | 27.2 | 3.8 (0.92 to 6.6) |
| Pain score after pain relief (447/347*) | 26.7 | 20.3 | 6.4 (3.5 to 9.4) |
| Missing AUC values not imputed | |||
| Satisfaction with pain relief during active labour (394/290) | 27.2 | 37.6 | −10.3 (−14.6 to −6.1) |
| Satisfaction with pain relief after pain relief (316/198†*) | 25.5 | 41.3 | −15.7 (−20.2 to −11.2) |
| Pain during active labour (438/354) | 29.7 | 24.9 | 4.9 (1.7 to 8.1) |
| Pain score after pain relief (345/220†) | 27.8 | 21.0 | 7.0 (3.3 to 10.7) |
*No who actually received pain relief.
†No who reported sufficient scores to calculate AUC and received pain relief.
