Association between preoperative quality of life (QoL) and postoperative complications after gastrectomy for gastric carcinoma.

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
purposeQuality of life (QoL) assessments in surgical practice have traditionally focused on postoperative recovery and long-term outcomes. This study evaluated the predictive value of preoperative QoL for postoperative complications.
methodsWe retrospectively analyzed the prospectively collected data from 908 patients who underwent gastrectomy for gastric carcinoma. Preoperative QoL was measured using the EORTC QLQ-C30 and STO22 questionnaires. A multivariate logistic regression was used to develop a predictive model, and model performance was assessed with a receiver operating characteristic (ROC) curve.
resultsDistal gastrectomy was performed in 763 patients (84.0%) and total gastrectomy in 145 patients (16.0%). Postoperative complications occurred in 189 patients (20.8%); local and systemic complications were observed in 160 (17.6%) and 48 (5.3%) patients, respectively, with some overlap. Patients with complications had significantly lower preoperative QoL scores across multiple functional and symptom domains. The predictive model identified global health status, stomach pain, anxiety, and body image as key indicators for complications, with an area under the ROC curve of 0.630 (95% CI 0.583-0.676). High-risk QoL classification by the model was an independent predictor of complications after adjusting for clinical risk factors.
conclusionPreoperative QoL, reflected in multiple functional and symptom domains, is associated with increased postoperative complications. Early identification of high-risk patients may facilitate targeted interventions to improve surgical outcomes.
