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

We designed a retrospective cohort study using the Diagnosis Procedure Combination database, a national inpatient database for acute-care inpatients in Japan, to examine whether recent global diagnostic criteria for preeclampsia, phenotypes of hypertensive disorders of pregnancy (HDP) and features of the disease are useful as predictors of placental abruption and whether other risk factors are associated with the onset of placental abruption. A total of 85,858 hospitalized patients with a diagnosis of HDP who gave birth during hospitalization between July 2010 and March 2018 were included in this study. We examined the associations between the occurrence of placental abruption after hospitalization and several factors, including gestational age (GA) at placental abruption onset, HDP subtypes, GA on admission, maternal age, body mass index, smoking, multiple pregnancy, prelabor rupture of membranes, diabetes mellitus, emergency admission by ambulance, and consciousness, using a multivariate logistic regression analysis. Placental abruption occurred in 541 patients (0.63%) after hospital admission, and the occurrence increased acutely after 32 weeks GA. A decrease in abruption was significantly associated with maternal BMI on admission (≥30 kg/m
