Effect of hospital volume on maternal outcomes in women with prior cesarean delivery undergoing trial of labor.
Article in American journal of epidemiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
The authors examined the association between hospital volume of vaginal birth after cesarean section (VBAC) and VBAC failure, uterine rupture, and maternal morbidity. This was a secondary analysis of data from a retrospective cohort study carried out from 1995 to 2000. Trained nurses extracted detailed information from the medical records of more than 25,000 women with a prior cesarean delivery from 17 community and tertiary-care hospitals in the northeastern United States. The study sample included 12,844 women with prior cesarean section who attempted vaginal delivery with a singleton birth. Annual hospital VBAC volume was divided into tertiles. Primary outcomes included VBAC failure, uterine rupture, and a composite measure of maternal morbidity. The authors used multivariable logistic regression to assess the association between hospital VBAC volume and adverse VBAC outcomes after controlling for confounders. The authors did not find evidence of an association between hospital VBAC volume and the likelihood of adverse outcomes in VBAC after adjustment for patient mix. Other risk factors consistent with prior research were identified, including induction of labor, >/=2 prior cesarean deliveries, preeclampsia, diabetes mellitus, and high birth weight. Prior vaginal delivery was protective against adverse VBAC outcomes. The risk of an adverse VBAC outcome in low-volume hospitals was comparable to that in high-volume hospitals.
