Summary of findings for the main comparison. Intermittent ausculation of fetal heart rate in labour for fetal well‐being ‐ Intermittent electronic fetal monitoring (CTG) versus routine Pinard (outcomes for the baby).
Intermittent ausculation of fetal heart rate in labour for fetal well‐being ‐ Intermittent electronic fetal monitoring (CTG) (inconsistent/ opportunistic paper tracing) versus routine Pinard (outcomes for the baby). | ||||||
Patient or population: women in established labour and their babies. Setting: all studies were conducted in Africa (Zimbabwe and Uganda). Intervention: electronic fetal monitoring (CTG) without paper tracing. Comparison: routine Pinard. | ||||||

Risk with routine Pinard | Risk with Intermittent electronic fetal monitoring | |||||
Apgar < 7 at 5 minutes | 29 per 1000 | 19 per 1000 (7 to 52) | RR 0.66 (0.24 to 1.83) | 633 (1 RCT) | ⊕⊕⊝⊝ VERY LOW 1,2 | Low event rate. Study reported Apgar score < 6 at 5 minutes. |
Cord blood acidosis | 0 per 1000 | 0 per 1000 (0 to 0) | not estimable | (0 studies) | No data reported for cord blood acidosis in the included studies. | |

*The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval; RR: Risk ratio; OR: Odds ratio; | ||||||
GRADE Working Group grades of evidence High quality: we are very confident that the true effect lies close to that of the estimate of the effect Moderate quality: we are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different Low quality: our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect Very low quality: we have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect |
1 Blinding of participants and health professionals not possible; high risk of performance bias and it is unclear if outcome assessors were blinded. Downgraded one level.
2 Evidence of imprecision; single trial with low event rate and wide 95% CI crossing the line of no effect. Downgraded two levels.
3 Evidence of imprecision, evidence based on a single trial with low event rates. Downgraded one level.
