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
backgroundNew-onset sarcopenia may develop after gastrectomy even in patients with normal muscle mass, but its detection in routine practice remains challenging. This study evaluated body composition changes after gastrectomy and identified clinical parameters associated with sarcopenia development.
methodsThis retrospective study included gastric cancer patients who underwent gastrectomy between 2009 and 2023. Body composition, including body weight (BW), skeletal muscle index (SMI), visceral fat area (VFA), and subcutaneous fat area (SFA), was assessed using CT images obtained preoperatively and 1 year postoperatively. Postoperative sarcopenia was defined as new-onset sarcopenia in patients without preoperative sarcopenia.
resultsAmong 1932 patients, mean percent changes in BW, SMI, VFA, and SFA at 1 year after gastrectomy were - 9.8%, + 1.0%, - 52.8%, and - 34.3%, respectively. Of 1259 preoperative non-sarcopenic patients, 145 (11.5%) developed postoperative sarcopenia and had significantly worse overall survival than those who maintained non-sarcopenia (HR, 2.516; 95% CI, 1.560-4.058; P < 0.001). Among these patients, recurrence incidence in those with stage II or III disease did not differ (Gray's test, P = 0.294), whereas post-recurrence survival was significantly worse in those with postoperative sarcopenia (log-rank, P < 0.001). Four clinical parameters (sex, age ≥ 60, extent of gastrectomy, and BW loss ≥ 8 kg) showed acceptable discrimination for identifying postoperative sarcopenia (simplified risk model; AUROC, 0.792; 95% CI, 0.755-0.829; P < 0.001).
conclusionsNew-onset sarcopenia 1 year after gastrectomy was independently associated with poor survival, underscoring its oncologic relevance. Simple clinical parameters may help identify high-risk patients and guide nutritional or exercise interventions.
