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 assess the efficacy of uterine artery embolization (UAE) for the management of primary postpartum hemorrhage (PPH) and to determine the factors associated with clinical outcomes especially in relation to the ovarian artery.

methodsA retrospective analysis of 33 patients who underwent UAE for primary PPH was performed. Clinical data were used regarding maternal characteristics, cause of bleeding, mode of delivery, bleeding onset after delivery, risk factors for PPH, presence of coagulopathy, details regarding the UAE procedure, and types of ovarian artery flow. We defined two types of ovarian artery flow by initial aortography before UAE (Type A: ovarian artery flow arose directly from the aorta to the uterine artery; Type B: ovarian artery flow that did not obviously arise from the aorta). Clinical success was defined as cessation of bleeding after UAE without the need for hysterectomy. Univariate analysis was performed to determine factors related to clinical outcomes.

resultsThe major indication of UAE was uterine atony (82%; 27/33). Extravasation of contrast medium was observed in 15 (45%) patients. The clinical success rate was 85% (28/33). In five patients, embolization failed, and these patients were managed by hysterectomy. Univariate analysis showed that retained placental tissue (p < 0.001), type of ovarian artery (p < 0.001) and the existence of extravasation of contrast medium (p = 0.049) were related to the clinical success rate.

conclusionThe clinical success rate was 85% (28/33), and some PPH patients were thought to need ovarian artery embolization in addition to UAE. Advances in knowledge: Initial aortography before UAE may be useful to predict the failure of UAE and the need of ovarian artery embolization. Obvious ovarian arterial blood flow to the uterus by aortography could be a warning sign.
