Disparities in overall survival of gastric cancer patients after radical gastrectomy: an age and rural-urban residence-based cohort study with propensity score matching analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study estimated overall survival (OS) among gastric cancer patients stratified by age and rural-urban residence after radical gastrectomy. Patients (n = 286) undergoing curative gastrectomy were categorized into four groups based on age (older ≥ 60 years or younger < 60 years) and residence (rural or urban), including rural older (G1), urban older (G2), rural younger (G3) and urban younger (G4) groups. G1 presented with significantly more males, upper stomach cancers and total gastrectomies, while less patients receiving ≥ 4 cycles of adjuvant chemotherapy. The 5-year OS rates were 39.9% for G1, 61.1% for G2, 73.1% for G3, and 71.2% for G4, with a median OS of 47 months in G1 and not reached for other groups. OS was significantly worse in G1 than other groups (P < 0.05). Multivariate Cox regression identified age, type of gastrectomy, adjuvant chemotherapy, perineural invasion, pT category and pN category as independent prognostic factors. After propensity score matching, rural older patients continued to show significantly inferior OS compared to urban older (hazard ratio = 2.269 [1.274-4.042], P = 0.005) and rural younger (hazard ratio = 2.103 [1.116-3.961], P = 0.021) patients. Rural older patients suffered poorer OS after radical gastrectomy, highlighting the need for special attention and comprehensive treatment strategies.
