Gastric Cancer in the Lesser and Greater Curvature: A Comparative Analysis from a Single Western Center.
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
BACKGROUND/
aimTo date, the different clinicopathological characteristics of gastric cancer (GC) in the lesser curvature and greater curvature remain unclear. The aim of this study was to investigate the different features of the tumors in the two sites and provide new strategy for a tailored therapy. PATIENTS AND
methodsBetween January 2003 and December 2019, 121 patients with GC located in the lesser or greater curvature were surgically treated with curative intent. Data about clinico-pathological features were retrospectively analyzed. In addition, we analyzed the different lymph node patterns according to the lymph node (LN) metastasis between the two groups of patients.
resultsNo statistically significant differences were found regarding the 5-year overall survival (5y-OS) and 5y disease-free survival (5y-DFS) between patients with GC in the two sites (p=0.94 and p=0.98, respectively). Considering TNM pathological stage, patients with GC in the lesser curvature in stage II and III, showed a worse survival than those with GC in the greater curvature (stage II 5y-OS: 80 vs. 100% and stage III 5y-OS: 18.9 vs. 55.5%). Considering the median value of metastasis LNs, GC in the greater curvature metastasized more often to LN stations no. 8, 10, and 11, whereas GC in the lesser curvature to LN stations no. 8, 9, and 12.
conclusionGC in the lesser curvature showed a worse prognosis than GC in the greater curvature. Therefore, GC in the lesser curvature could undergo a more aggressive surgery, including an extended lymphadenectomy, and a close follow-up.
