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 examine the association of clinical chorioamnionitis on cesarean delivery in a national sample of hospital discharges. DATA SOURCE: Hospital discharge data from the 1998-2010 Nationwide Inpatient Sample. STUDY

designWe performed a cross-sectional study and general linear modeling was used to determine the association of clinical chorioamnionitis on risk of cesarean delivery. PRINCIPAL

findingsA total of 10,843,682 deliveries and 51,799,431 nationally weighted deliveries were identified. Clinical chorioamnionitis was present in 2.9 percent of cesarean and 1.3 percent of vaginal deliveries (p < .001). In multivariate analysis, clinical chorioamnionitis was associated with a 1.39-fold increased risk of cesarean delivery. Compared with women without clinical chorioamnionitis at an urban/teaching hospital, women with clinical chorioamnionitis at an urban/teaching, urban/nonteaching, and rural hospital were 1.4-1.5 times more likely to have cesarean delivery. Compared with women without clinical chorioamnionitis in the Midwest, the relative risk for cesarean in women with clinical chorioamnionitis was 1.54 for women in the South, 1.47 in the Northeast, 1.39 in the Midwest, and 1.34 in the West.

conclusionsWomen with clinical chorioamnionitis were more likely to have cesarean delivery than those without clinical chorioamnionitis, and the risk of cesarean delivery varied significantly by hospital location, teaching status, and U.S. region.
