Predictive nomogram for postsurgical gastroparesis syndrome and survival outcomes following distal gastrectomy: an in-depth analysis.
Trial report in Surgical endoscopy, 2026. 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
backgroundPostsurgical gastroparesis syndrome (PGS) is a common complication after distal gastrectomy that impairs quality of life and increases healthcare costs, yet its risk factors and long-term prognostic impact remain unclear.
objectiveTo identify PGS risk factors after radical distal gastrectomy, develop and validate a model, and assess its association with long-term survival.
methodsWe retrospectively analyzed patients undergoing radical distal gastrectomy at Qilu Hospital of Shandong University between January 2012 and December 2023. Patients were assigned to training and validation cohorts by surgery date. Logistic regression was used to identify independent risk factors and develop a PGS prediction nomogram. Propensity score overlap weighting (PSOW) was applied to reduce confounding, and the prognostic impact of PGS was assessed using weighted Kaplan-Meier analysis, log-rank tests, and Cox regression.
resultsA total of 2490 patients were included (training cohort: 1934 [77.7%]; validation cohort: 556 [22.3%]), among whom 238 developed PGS (training cohort: 187). Independent risk factors included prolonged operative time (OR = 1.01), intellectual work (OR = 2.02), well-controlled diabetes (OR = 3.10), poorly controlled diabetes (OR = 4.95), history of constipation (OR = 2.46), preoperative pyloric obstruction (OR = 3.77), perioperative psychiatric symptoms (OR = 4.60), and Billroth II (OR = 3.07) or Roux-en-Y anastomosis (OR = 6.29). Protective factors were higher preoperative plasma albumin (OR = 0.96) and laparoscopic surgery (OR = 0.47) (all p < 0.05). The nomogram showed good discrimination and calibration, with AUCs of 0.81 for the training cohort, 0.81 for internal validation, and 0.82 for temporal validation. Patients with PGS exhibited significantly worse survival outcomes, and PGS was independently associated with poorer survival in the overlap-weighted analysis (HR 1.41, 95% CI 1.12-1.79, p = 0.004).
conclusionsThe nomogram prediction model based on the risk factors for PGS occurrence has potential value in predicting the onset of PGS. PGS is significantly associated with the prognosis of patients after radical surgery for distal gastric cancer. CLINICAL
