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

backgroundPapillary adenocarcinoma (Pap) is a relatively rare histological subtype of differentiated adenocarcinoma, and its biological behavior has not been fully elucidated. The present study aimed to clarify the clinicopathological characteristics of Pap.

methodsThis study retrospectively included 1701 patients with differentiated-type gastric cancer who underwent gastrectomy at our institution between 2009 and 2021. Clinicopathological characteristics, recurrence patterns, and survival outcomes were compared between the two groups.

resultsPatients in the Pap group were older and showed higher rates of venous-and lymphatic invasion, as well as more advanced clinical and pathological stages. In the multivariate analysis of cumulative recurrence, histological type was identified as an independent predictor (HR 2.051, p = 0.037). The most common initial site of recurrence was the liver in both groups, with a significantly higher incidence observed in the Pap group (p < 0.001). In the multivariate analysis of overall survival, histological type was also identified as an independent prognostic factor (HR 1.962, p = 0.044).

conclusionsPap showed poorer survival than the Tub group, with a particularly higher incidence of liver metastasis recurrence.
