Psychometric testing of the abdominal surgery impact scale in the Turkish population.
Article in BMC surgery, 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
backgroundPostsurgery recovery is a multifaceted and dynamic process. Recent reports recommend using condition-specific patient-reported outcome measures to evaluate surgical recovery. This study aimed to examine the psychometric properties of the Abdominal Surgery Impact Scale (ASIS) in the Turkish population.
methodsThis methodological study included 181 patients who primarily underwent minor or intermediate abdominal procedures. The scale was applied twice: in the early postoperative period and one month postoperatively. Content validity, construct validity, item analysis, internal consistency, and responsiveness were evaluated.
resultsMost participants underwent hernia surgery (44.2%) or cholecystectomy (41.4%); only 7.7% had major surgery. Responsiveness analysis showed that mean total ASIS-TR scores increased significantly (p < 0.001) from the early postoperative period (77.71 ± 23.60) to one month postoperatively (116.08 ± 14.50). The ceiling effect of the one-month postoperative scale was 40.3%. Item-total correlations ranged from 0.33 to 0.75. Internal consistency was high (McDonald's ω = 0.91, Cronbach's α = 0.91), with domain ω values ranging from 0.51 for Visceral Function to 0.94 for Psychological Function. The fit indices at the two time points supported construct validity. Early fit index values were as follows: χ
conclusionThe ASIS-TR demonstrated acceptable to high reliability, validity, and responsiveness. However, these findings should be interpreted cautiously given the predominance of minor surgical procedures, the presence of a ceiling effect, and the low reliability of the Visceral Function domain. Future research involving multicentre recruitment should be conducted with patient populations undergoing major gastrointestinal surgeries, and convergent validity and test-retest reliability should be evaluated.
