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

purposeAntepartum hemorrhage (APH) in women with placenta previa (PP) has been associated with increased perinatal complications. The present study aims to evaluate the maternal and neonatal outcomes, and risk factors related to this condition.

methodsThis retrospective study was conducted in the Obstetrics and Gynecology Department of the Second Affiliated Hospital of Army Military Medical University from January 2016 to September 2019, which included all women with PP. The clinical and ultrasound features in patients with or without APH were compared.

resultsThere were 233 women with APH and 302 women without APH in the cohort. Most of the women with APH were prone to adverse maternal and neonatal outcomes. In the logistic regression analysis, cervical length was inversely correlated to APH (OR: 0.972, 95% CI: 0.952~0.993), while complete PP increased the risk for APH (OR: 2.121, 95% CI: 1.208~3.732). Furthermore, the anterior placenta increased the risk for APH (OR: 1.664, 95% CI: 1.139~2.430), the partial absence of the over lying myometrium increased the risk for APH (OR: 2.015, 95% CI: 1.293~3.141), and the previous history of uterine artery embolization (UAE) increased the highest risk for APH (OR: 11.706, 95% CI: 1.424~96.195).

conclusionObstetricians should be aware of the increased risk of adverse pregnancy outcomes related to APH in women with complete PP, short cervical length, anterior placenta, and partially absent over lying myometrium. Prior UAE is a novel risk factor associated with increased prevalence of APH.
