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

<p>Objectives: The aim of this study was to evaluate the clinical outcomes of salvage surgery for localized recurrent ovarian clear cell carcinoma (OCCC), a chemoresistant subtype with poor prognosis.

designWe retrospectively analyzed 75 patients who underwent primary surgery for OCCC between January 1996 and December 2022. PARTICIPANTS AND

methodsTwenty-two patients experienced recurrence after complete resection, of whom 10 met the institutional criteria for localized, resectable recurrence and underwent 17 salvage procedures. The clinical characteristics, surgical outcomes, and survival data were also reviewed. Progression-free survival (PFS) and post-recurrence survival (PRS) were analyzed using the Kaplan-Meier method.

resultsComplete resection was achieved in all procedures. The median PFS after the first salvage surgery was 30 months and the median PRS was not reached. Four patients underwent a second and third salvage surgery, with several achieving long-term disease control or remaining disease-free. At the last follow-up, 7 of the 10 patients were alive without evidence of disease, including multiple survivors beyond five years. In contrast, the chemotherapy-only cohort (n = 12) showed a median PFS of 5 months and PRS of 10 months. No perioperative mortality occurred, and all complications were Clavien-Dindo grade II or lower.

conclusionSalvage surgery for localized recurrent OCCC can achieve durable disease control and long-term survival in carefully selected patients, particularly when complete resection is possible. Even in chemoresistant diseases, repeated cytoreductive surgery may offer meaningful benefits, supporting its role as a viable treatment option within a multidisciplinary framework. </p>.
