Rupture of a Nongravid Unicornuate Uterus Following Failed Induction of a Noncommunicating Rudimentary Horn Pregnancy: A Rare Case Report.

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
Pregnancy within a non-communicating rudimentary horn is a rare and potentially life-threatening form of ectopic gestation associated with Müllerian duct anomalies. Diagnosis is frequently delayed because ultrasonographic findings may mimic those of a normal intrauterine pregnancy. We report the case of a 24-year-old gravida 2 para 1 woman who presented with a 14-week-and-6-day missed abortion initially interpreted as intrauterine pregnancy. Medical induction with misoprostol failed to achieve cervical dilatation; a mechanical cervical ripening attempt with a transcervical Foley catheter also failed, and oxytocin infusion was subsequently started. Shortly afterward the patient developed severe abdominal pain with hemodynamic compromise. Emergency laparotomy demonstrated a right-sided non-communicating rudimentary horn pregnancy within a unicornuate uterus. The gravid rudimentary horn remained intact, while a full-thickness rupture was identified in the posterolateral wall of the nongravid unicornuate uterine cavity; direct intraoperative inspection confirmed this rupture to be iatrogenic, resulting from a false passage created during Foley catheter insertion and propagated by subsequent oxytocin-induced contractions. Excision of the rudimentary horn, together with the ipsilateral fallopian tube, and repair of the uterine rupture were successfully performed. Persistent failed induction in a presumed second-trimester missed abortion should prompt evaluation for obstructive Müllerian anomalies, including noncommunicating rudimentary horn pregnancy, before further mechanical instrumentation is attempted.
