Prediction of Positive Angiogram Using Enhanced Computed Tomography in Postpartum Hemorrhage: A Retrospective Multicentered Study.

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
aimThis study aimed to determine the accuracy of active arterial hemorrhage (AAH) on computed tomography (CT) in predicting the need for embolization in postpartum hemorrhage (PPH).
methodsIn a multicentered retrospective observational study, we reviewed the medical records of PPH patients between April 2010 and May 2020. We included patients who initially underwent enhanced CT and were subsequently classified as AAH+ or AAH- on CT. AAH+ on angiogram and embolization was used as a positive reference standard. A multiple logistic regression model evaluated AAH on CT as a predictor for embolization. We assessed AAH+ on CT supplied by extrauterine arteries.
resultsOf 231 PPH patients, 94 underwent enhanced CT. AAH+ and AAH- on CT consisted of 44 and 50 patients, respectively. Of AAH+ on CT patients, 32 (72.7%) underwent angiography and embolization. The sensitivity, specificity, and positive and negative predictive values of AAH on CT were 95.6%, 69.0%, 50.0%, and 98.0%, respectively. A multiple logistic regression model revealed that AAH on CT was an independent predictor of embolization (odds ratio=9.31, confidence interval=2.85-30.50, p<0.01). Sites of AAH on CT were the vagina (n=7), intraperitoneal (n=3), and abdominal wall (n=3), except for intrauterine sites.
conclusionEnhanced CT showed high sensitivity and had a negative predictive value for predicting AAH+ on angiogram and embolization; this may be useful in ruling out the necessity for angiography. Active arterial hemorrhage on CT may predict embolization and identify the precise bleeding site.
