The positive impact of surgeon specialization on survival for gastric cancer patients after surgery with curative intent.
Article in Gastric cancer : official journal of the International Gastric Cancer Association and the Japanese Gastric Cancer Association, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05280665 (The Impact of Specialization on Clinical Outcomes in Gastric Cancer Surgery), which is not on this map. Cited by 15 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
backgroundMany studies have affirmed the survival benefit for cancer patients treated by specialized surgeons.
methodsA total of 967 patients with gastric cancer (GC) who underwent gastrectomy with curative intent in our center were enrolled. Patients were categorized into two groups based on surgeon specialization: the specialized group (SG) and nonspecialized group (NSG). To overcome bias due to the different distribution of covariates for the two groups, a one-to-one match was applied using propensity score analysis. After matching, prognosis and recurrence data were analyzed.
resultsAfter one-to-one matching, 261 patients in the SG and 261 patients in the NSG had the same characteristics excluding factors associated with surgery. In multivariate analysis for the whole study series, surgeon specialization was an independent prognostic factor for GC patients after surgery. Patients in the SG demonstrated a significantly higher 5-year overall survival than those in the NSG (50.7 vs. 37.2 %, p = 0.001). With the strata analysis, significant prognostic differences between the two groups were only observed in patients at stage IIIa-b or N1-2. The proportion of locoregional recurrence was greater in the NSG than in the SG.
conclusionGC patients treated by specialized surgeons tended to have a better prognosis and lower locoregional recurrence rate. Surgeon specialization was an independent prognostic factor for GC patients after surgery. GC should be treated by specialized surgeons in large-volume centers.
