Second-trimester ovarian pregnancy mimicking intrauterine pregnancy and causing hemorrhagic shock in surgery: a case report and review of the literature.
Review in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundOvarian pregnancies at advanced gestational ages are exceedingly rare in clinical practice. The infrequency of this condition, coupled with the nonspecific nature of its symptoms and signs, renders preoperative diagnosis extremely challenging. CASE PRESENTATION: A 29-year-old pregnant woman, G7P3 in second trimester, was transferred to our center for pregnancy termination. She had a history of three cesarean deliveries and the pregnancy was uneventful. Ethacridine lactate was administered and she experienced abdominal pain. Uterine rupture was suspected and an urgent laparotomy was performed, during which the patient was finally diagnosed with an ovarian pregnancy. Given the patient was thin and anemic, coupled with severe adhesions, abundant blood supply, and significant blood loss encountered during surgery, she developed hemorrhagic shock. The left adnexa were removed, and the patient subsequently had a favorable postoperative recovery.
conclusionOvarian pregnancies at advanced gestational ages are rare cases and difficult to diagnose. When the manifestations do not correspond with those of a typical intrauterine pregnancy, the potential for this rare form of ectopic pregnancy should be considered.
