Comparison of ovarian torsion between pregnant and non-pregnant women at reproductive ages: sonographic and pathological findings.

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
backgroundDifferences in the ultrasonographic features and histological diagnosis of ovarian torsion in pregnant and non-pregnant women have not been defined. A better characterization of these features may help improve the accuracy of preoperative diagnosis. The present study aimed to compare the clinical characteristics, sonographic findings, operative procedures, and histological spectrum of ovarian torsion in pregnant and non-pregnant women.
methodsThis was a retrospective investigation of female patients at reproductive age with ovarian torsion between January 2010 and May 2017. Each patient received a detailed preoperative ultrasound, and the diagnosis was confirmed by surgery. The clinical characteristics, ultrasonic features, operative procedures, and histological diagnosis of ovarian torsion were retrieved from medical records and were compared in non-pregnant and pregnant patients according to the method of conception.
resultsThe overall preoperative ultrasonic detection rate of ovarian torsion was 0.84, which was significantly different between pregnant and non-pregnant women. The presence of ovarian edema and abnormal adnexal positions also differed between pregnant and non-pregnant women. The ultrasonic features were not significantly different between the two pregnant sub-groups. The most common histologic diagnoses in the pregnant group and the non-pregnant group were a normal ovary and teratoma, respectively. The incidence of ovarian neoplasm was significantly lower in pregnant women. There were significant differences in the surgical procedures between the groups based on neoplastic or non-neoplastic lesions.
conclusionsOvarian edema, absence/decreased blood flow in the ovary, and the whirlpool sign were reliable ultrasonic markers for ovarian torsion at reproductive ages. The preoperative ultrasonic detection rate of ovarian torsion was higher in pregnant women, and ovarian edema was more common. The clinical features of ovarian torsion in pregnant women were similar, independent of the method of conception. In women with ovarian torsion, the incidence of non-neoplastic lesions was more frequent in pregnant women, whereas neoplastic lesions were more common in non-pregnant women. Ultrasonography provides useful parameters for the preclinical diagnosis of ovarian torsion to improve patient management.
