Improving diagnostic accuracy of ovarian torsion using contrast-enhanced ultrasound: A prospective comparative clinical study of performance diagnosis.
Article in International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
objectiveThis study evaluates the diagnostic performance of contrast-enhanced ultrasound (CEUS) for improving diagnosis of adnexal torsion in women with acute abdominal pain.
methodsThis was a pilot study of the diagnostic accuracy of CEUS for the detection of adnexal torsion. All women in our center with planned surgery for suspicion of adnexal torsion were included. The final diagnosis was confirmed during surgical intervention to classify "torsion" and "control" groups. Qualitative imaging analyses were performed blindly of the final diagnosis by an expert and nonexpert obstetrician and gynecologist (Obgyn).
resultsSix ovaries were included in the torsion group and eight ovaries in the control group. A total of 476 images from 14 included cases were analyzed by one expert and 34 ObGyn. The sensitivity was 100% (confidence interval [CI] 95% [59-100]) and 84.3% (CI 95% [78.7-88.9]) and the specificity 86% (CI 95% [42-100]) and 89.8% (CI 95% [85.4-93.2]) for expert and nonexpert Obgyn, respectively.
conclusionThe diagnostic performance of CEUS to diagnose adnexal torsion is high.
