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

Giant ovarian mucinous cystadenomas have become uncommon due to earlier detection, yet they may closely mimic malignancy on imaging. We report a 45-year-old woman with progressive abdominal enlargement and inability to lose weight, who remained otherwise asymptomatic. Imaging revealed a multiloculated right adnexal mass with thick septations and apparent solid components, associated with minimal ascites and right grade III hydronephrosis. Based on imaging features, the mass was classified as O-RADS 5, while serum tumor markers were within normal limits. Exploratory laparotomy demonstrated a 35-cm right ovarian mass with marked anatomical distortion and dense Zühlke grade IV adhesions. The tumor was removed intact to avoid spillage, and intraoperative frozen section analysis confirmed benign pathology, guiding continuation of the planned procedure. Final histopathology revealed a benign mucinous cystadenoma. Postoperative recovery was uneventful. This case highlights the limitations of imaging in giant ovarian tumors and underscores the importance of a safety-oriented surgical approach.
