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

backgroundSmall cell carcinoma of the ovary, hypercalcemic type, is a rare, highly aggressive malignancy that predominantly affects young women and is associated with poor prognosis and limited treatment options. CASE PRESENTATION: We report the first documented case of small cell carcinoma of the ovary, hypercalcemic type, in a 30-year-old Pakistani woman who presented with abdominal pain, vomiting, weight loss, and biochemical evidence of hypercalcemia. Imaging revealed a large left adnexal mass measuring 9.3 cm × 10.7 cm × 9.7 cm. Subsequent histopathological and immunohistochemical analysis demonstrated characteristic features of small cell carcinoma of the ovary, hypercalcemic type with complete loss of SMARCA4 (BRG1) expression, confirming the diagnosis. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection, followed by multi-agent chemotherapy. Despite her initial response, she developed widespread metastatic disease with tumor infiltration of the abdominal wall and encasement of ileal loops. This ultimately resulted in a contained ileal perforation and the formation of an enterocutaneous fistula-an uncommon and previously unreported complication of small cell carcinoma of the ovary, hypercalcemic type.

conclusionThis case highlights the diagnostic and therapeutic challenges associated with small cell carcinoma of the ovary, hypercalcemic type, and underscores the critical role of SMARCA4 immunohistochemistry in confirming the diagnosis, particularly in resource-limited settings where molecular testing may not be widely accessible.
