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

backgroundLymph node dissection is a standardized procedure in gastric cancer surgery. Typically, lymph node metastasis begins in the perigastric (PG) region and then extends to the extraperigastric (EP) region. However, in some circumstances, skip lymph node metastasis occurs in the EP region without involvement of the PG lymph nodes. This study aims to investigate the clinical significance of skip lymph node metastasis in gastric cancer.

methodsA total of 1,055 patients who underwent curative gastrectomy for primary gastric cancer with pathological lymph node metastasis were analyzed. Patients were categorized into three groups: the PG-only group, the PG + EP group, and the skip group. The clinicopathologic characteristics and prognosis were analyzed.

resultsThe incidence of skip lymph node metastasis was 3.9% (41 of 1,055 patients). The skip group had a higher proportion of females compared to both the PG-only group (43.9% vs. 27.5%, p = 0.025) and the PG + EP group (43.9% vs. 26.5%, p = 0.017). Additionally, the skip group showed a higher proportion of intestinal-type tumors compared to the PG-only group (68.3% vs. 50.6%, p = 0.029) and the PG + EP group (68.3% vs. 40.2%, p = 0.001). Disease-free survival and overall survival in the skip group were similar to those in the PG-only group but significantly better than those in the PG + EP group.

conclusionsSkip lymph node metastasis is uncommon, and it is associated with a higher proportion of females and intestinal-type tumors. The prognosis of the skip group was comparable to the PG-only group and significantly better than that of the PG + EP group.
