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
Objectives: The aim of this study was to perform a cross-cultural adaptation and psychometric evaluation of the Quality of Recovery-15 (QoR-15) questionnaire in Türkiye. Methods: The QoR-15 was translated into Turkish through a rigorous process involving independent translations, consensus, forward-backward translation, and review. The questionnaire was administered to patients undergoing major abdominal surgery preoperatively and on postoperative days 1, 7, and 30. Reliability was assessed using Cronbach's α, McDonald's Omega, and the inter-item correlation coefficient. Construct validity was evaluated using confirmatory factor analysis (CFA), and responsiveness was analyzed using Cohen's effect size and the standardized response mean (SRM). Results: A total of 510 patients participated in the study; 335 (65.69%) were <65 years old, and 279 (54.71%) were male. The Turkish version of QoR-15 (QoR-15T) demonstrated good internal consistency, with Cronbach's α values of 0.896 and 0.888 for preoperative and postoperative administrations, respectively, and McDonald's Omega coefficients of 0.894 and 0.878. Confirmatory factor analysis confirmed the two-factor (two-dimensional) structure of the QoR-15T. The comparative fit indices for Models 1 and 2 were 0.970 and 0.991, respectively. QoR-15T showed responsiveness to changes in health status, with Cohen's effect size (1.22) and the standardized response mean (1.18) indicating its ability to detect clinically important changes. Conclusion: The QoR-15T is a reliable, valid, and responsive questionnaire for assessing the quality of recovery in patients undergoing major abdominal surgery. Its ability to capture patients' perspectives and multidimensional aspects of recovery makes it a valuable tool for clinical and research purposes.
