Does prior ultrasonography affect the safety of induced abortion at or after 13 weeks' gestation? A retrospective 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
introductionWe aimed to assess whether ultrasonography prior to dilation and evacuation or medical abortion ≥13 weeks was correlated with safety. MATERIAL AND
methodsWe conducted a retrospective chart review of patients undergoing abortion ≥13 weeks at eight sites in Nepal from 2015 to 2019.
resultsWe included 2294 women undergoing abortion ≥13 weeks (no upper gestational age limit); 593 underwent dilation and evacuation and 1701 had a medical abortion. Demographics differed by procedure for parity (19% vs 33% nulliparous, dilation and evacuation, and medical abortion) and gestational age (90% vs 52% were 13-15 weeks, dilation and evacuation, and medical abortion). Ultrasonography was performed in 81% of cases overall. Complications were rare (<1% of dilations and evacuations, 1.4% of medical abortions). The most common adverse events with dilation and evacuation were hemorrhage and cervical laceration; three women required re-aspiration. Following medical abortion, 13.5% had retained products, 12.9% with prior ultrasound and 16.3% who had not had an ultrasound. Hemorrhage and severe side-effects occurred at similarly low rates regardless of whether ultrasonography was performed. In a logistic regression model where patient characteristics and case clustering within facilities were controlled for, we found a correlation between ultrasonography and complications when retained placenta was included in the model, but there was no correlation between ultrasonography and complications when retained placenta was excluded.
conclusionsThis study confirms low complication rates among women having an abortion ≥13 weeks' gestation in healthcare facilities. Settings without universal availability of ultrasound may still maintain low, comparable complication rates.
