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

Background: Laparoscopic surgery for malignant tumours occasionally results in recurrence at the trocar insertion site or port-site metastasis (PSM). We report on a patient requiring emergency laparoscopic surgery for an ovarian tumour with a review of the relevant literature. Case Report: A 42-year-old woman developed sudden abdominal pain and underwent laparoscopic right adnexectomy because of a suspected ovarian cystic tumour rupture. The postoperative histological diagnosis was a mucinous borderline ovarian tumour; however, an undifferentiated carcinoma was detected at the port site eight months after the initial surgery. The histopathological diagnosis of the abdominal wall tumour at the port site differed from intraoperative pathological findings, which was contradictory to PSM definition. Postoperatively, she received three systemic chemotherapy courses but died consequent to tumour metastasis. Conclusion: This is an atypical PSM case with histopathological differences from the initial tumour. Careful preoperative diagnosis and intraoperative attention are essential in such cases.
