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

The etiology of OT is largely unknown. Any predisposition to rotation of the infundibulopelvic ligament and utero-ovarian ligament should be considered a possible etiology. Information with respect to ovarian torsion (OT) among pregnant is underreported and based on small studies. We aim to compare characteristics of confirmed OT to laparoscopies performed for the indication of suspected OT, in which no OT was found among pregnant women. This is a retrospective case-control study. We included pregnant women who underwent laparoscopy for a suspected OT between March 2011 and August 2020. Pregnant women with confirmed OT (torsion group) were compared to those without (no torsion group). There were 169 women with suspected OT. OT was confirmed in 140 (82.8%) women. There was higher proportion of assisted reproductive technology (ART) gestation in the torsion group [76 (54.3%) vs. 5 (17.2%), p < 0.001]. The rate of pregnant approaching evaluation within 8 h of symptoms onset was higher in the torsion group [57 (40.7%) vs. 2 (6.9%), p < 0.001]. The mean visual analogue score (VAS) was higher in the torsion group (8.5 vs. 7.1, p = 0.002). The mean pulse was lower in the torsion group (79 vs. 88 bpm, p < 0.001). From sonographic characteristics examined, the following was higher in the torsion group; mean maximal size of the ovary (70 mm in the torsion group vs. 54 mm in the no torsion group, p = 0.011). In a multivariable logistic regression analysis, number of hours of symptoms was negatively associated with AT [aOR, 95% CI 0.95 (0.91-0.98)] and pulse was negatively associated with OT [aOR, 95% CI 0.78 (0.63-0.95)]. Among the 29 cases in which no OT was found during laparoscopy, the following findings were noted: 16 (55.2%) no abnormality at all, 5 (17.2%) functional ovarian cyst, 2 (6.9%) mature teratoma and 6 cases of peritoneal adhesions (20.7%). The time from pain onset to approaching evaluation and women's pulse should be considered and acknowledged in the evaluation of OT during pregnancy.
