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

purposeThe role of conversion surgery for gastric cancer with peritoneal metastasis is unclear and there are no reliable biomarkers. We evaluated the outcomes of conversion surgery and the predictive value of inflammatory and nutritional markers.

methodsThe subjects of this retrospective analysis were 65 patients with massive peritoneal metastasis (P1b or P1c) from among 102 gastric cancer patients with positive peritoneal cytology or peritoneal metastasis, diagnosed by staging laparoscopy. We investigated the association between inflammatory and nutritional markers before treatment, including the neutrophil-to-lymphocyte ratio, the modified Glasgow prognostic score (mGPS), the prognostic nutritional index; and the feasibility of conversion surgery.

resultsConversion surgery was performed after chemotherapy in 14 of the 65 patients. Median survival was longer in the conversion surgery group than in the non-surgery group (30 vs. 9 months, P < 0.001). Multivariate analysis identified conversion surgery (HR 0.27, 95% CI 0.12-0.60) and mGPS 0 (HR 0.35, 95% CI 0.19-0.65) as independent prognostic factors. Patients with mGPS 0 were significantly more likely to undergo conversion surgery (P = 0.026).

conclusionsConversion surgery may be associated with improved survival for gastric cancer patients with unresectable peritoneal metastases. Moreover, mGPS may be a useful biomarker as a prognostic or selection-related factor.
