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

purposeTo evaluate the rates of vaginal birth after cesarean (VBAC) among parturients attempting preterm trial of labor following a cesarean delivery (TOLAC) vs. term TOLAC.

methodsA multicenter historic cohort study was conducted at two university-affiliated centers between August 2005 and March 2021. Parturients in their second delivery, attempting TOLAC after a single low segment transverse cesarean delivery were included. We retrospectively examined computerized medical records of all preterm (< 37 weeks) and term (37-42 weeks) births. Multifetal gestations and postterm deliveries (≥ 42 weeks) were excluded. A univariate analysis was conducted, followed by a multivariate analysis.

results4865 second deliveries following previous cesarean were identified: 212 (4.4%) preterm and 4653 (95.6%) term. Hypertensive disorders, diabetes and fertility treatments were significantly more prevalent in the preterm group. VBAC rate was significantly lower in preterm group (57.5 vs 79.7%., p < 0.01), including both spontaneous and vaginal-assisted deliveries. In multivariate analysis, preterm TOLAC was independently associated with TOLAC failure [adjusted odds ratio 2.24, [95% confidence interval 1.62-3.09]. Overall, maternal outcomes were favorable. Rates of uterine rupture, re-laparotomy and postpartum hemorrhage were comparable between groups. Neonatal outcomes were less favorable among the preterm group; however, preterm vs. term TOLAC was not associated with low 5 min Apgar score (aOR 1.76, 95% CI 0.92-3.40).

conclusionIn our study, VBAC rates were lower in preterm compared to term deliveries. Maternal outcomes were comparable. Neonatal outcomes were less favorable in the preterm group, more likely due to prematurity than delivery mode.
