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
backgroundThe longitudinal recovery process for postoperative quality of life (QOL) after gastrectomy remains incompletely understood. We prospectively evaluated temporal changes in QOL using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) and investigated predictors of poor postoperative QOL.
methodsThis prospective observational study enrolled 433 patients who underwent gastrectomy for primary gastric cancer between 2015 and 2020. Patients completed the PGSAS-45 questionnaire preoperatively and at 1 month, 6 months, 1 year, and > 5 years after surgery. Longitudinal changes in QOL were analyzed, and multivariable logistic regression was performed to identify predictors of poor postoperative QOL at 1 year after surgery.
resultsAll PGSAS-45 domains except the mental component summary (MCS) were significantly deteriorated at 1 month after surgery. Most domains recovered substantially between 1 and 6 months and changed little thereafter. MCS was the only domain that improved beyond the preoperative level. Independent predictors of poor total symptom score were major postoperative complications (Clavien-Dindo grade ≥ III; odds ratio [OR] 4.78, p = 0.013) and preoperative MCS < 46 (OR 2.45, p = 0.001). Preoperative physical component summary (PCS) < 46 (OR 2.01, p = 0.028) independently predicted poor quality of ingestion, while preoperative MCS < 46 (OR 2.81, p < 0.001) independently predicted greater dissatisfaction with daily life.
conclusionsPostoperative QOL recovered predominantly within the first 6 months after gastrectomy and remained largely stable thereafter. Preoperative PCS and MCS, together with major postoperative complications, were important determinants of postoperative QOL.
