1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo evaluate maternal and neonatal outcomes by attempted mode of operative delivery from a low station in the second stage of labor.

methodsRetrospective study of 2,518 women carrying singleton fetuses at 37 weeks of gestation or greater who underwent attempted forceps-assisted delivery, attempted vacuum-assisted vaginal delivery, or cesarean delivery from a low station in the second stage of labor. Primary outcomes were stratified by parity and included a maternal adverse outcome composite (postpartum hemorrhage, transfusion, endometritis, peripartum hysterectomy, or intensive care unit admission) and a neonatal adverse outcome composite (5-minute Apgar score less than 4, respiratory morbidity, neonatal intensive care unit admission, shoulder dystocia, birth trauma, or sepsis).

resultsIn nulliparous patients, the maternal adverse composite was not significantly different between women who underwent attempted forceps (12.1% compared with 10.8%, adjusted odds ratio [OR] 0.77, 95% confidence interval [CI] 0.40-1.34) or vacuum (8.3% compared with 10.8%, adjusted OR 0.68, 95% CI 0.40-1.16) delivery compared with cesarean delivery. Among parous women, the maternal adverse composite was not significantly different with attempted forceps (10.7% compared with 12.5%, adjusted OR 0.40, 95% CI 0.09-1.71) or vacuum (11.3% compared with 12.5%, adjusted OR 0.44, 95% CI 0.11-1.72) compared with cesarean delivery. Compared with neonates delivered by cesarean, the neonatal adverse composite was significantly lower among neonates born to nulliparous women who underwent attempted forceps (9.4% compared with 16.7%, adjusted OR 0.44, 95% CI 0.27-0.72) but not among those who underwent vacuum delivery (11.9% compared with 16.7%, adjusted OR 0.68, 95% CI 0.44-1.04). Among parous women, the neonatal adverse composite was not significantly different after attempted forceps (4.1% compared with 12.5%, adjusted OR 0.28, 95% CI 0.06-1.35) or vacuum (12.5% compared with 12.5%, adjusted OR 1.03, 95% CI 0.28-3.87) compared with cesarean delivery.

conclusionA trial of forceps delivery from a low station compared with cesarean delivery was associated with decreased neonatal morbidity among neonates born to nulliparous women. LEVEL OF EVIDENCE: II.
