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

backgroundAdvanced gastric cancer frequently recurs even after radical resection followed by adjuvant chemotherapy. The aim of this study was to evaluate the relationship between pathological infiltrative pattern (INF) and initial recurrence patterns in patients with stage II/III gastric cancer using a large multicenter database.

methodsWe retrospectively analyzed 1098 eligible patients who underwent curative gastrectomy for stage II/III gastric cancer at nine institutions between 2010 and 2014. Patients were categorized into the INF-a/b and INF-c groups and adjusted using propensity score matching.

resultsAfter propensity score matching, 686 patients (343 for each) were classified in the INF-a/b and INF-c groups. There were no significant differences in overall and disease-free survival between the two groups. In the INF-a/b group, frequencies of recurrence at the peritoneum, lymph node, and liver were equivalent. In contrast, the peritoneum was the most frequent site and accounted for 60% of the total recurrences in the INF-c group. The cumulative peritoneal recurrence rate was significantly higher in the INF-c group than in the INF-a/b group (hazard ratio 2.47). INF-c was a significant risk factor for peritoneal recurrences in most subgroups including age, sex, macroscopic type, tumor differentiation, and disease stage, and whether the postoperative treatment was given. Multivariate analysis identified INF-c as an independent risk factor for peritoneal recurrences. The cumulative liver recurrence rate was significantly higher in the INF-a/b group than in the INF-c group (hazard ratio 3.44).

conclusionsINF may represent an important predictor of recurrence patterns after curative resection of stage II/III gastric cancer.
