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
Background: The Mayo Clinic Vestibular Schwannoma Quality of Life (VSQOL) Index is a disease-specific instrument for assessing health-related quality of life (HRQoL) in patients with sporadic vestibular schwannoma (VS). To date, there is no validated Italian version of this questionnaire. Objectives: This study aimed to translate, culturally adapt, and validate the VSQOL Index Version 2 in Italian (Italian VSQOL Index) while assessing its psychometric properties. Methods: The VSQOL Index Version 2 was translated and culturally adapted according to the Functional Assessment of Chronic Illness Therapy (FACIT) methodology. A cohort of 39 Italian-speaking VS patients completed the Italian VSQOL Index alongside the Penn Acoustic Neuroma Quality of Life (PANQOL) Scale, the 36-Item Short Form Health Survey (SF-36), and the 21-Item Depression, Anxiety, and Stress Scale (DASS-21). Internal consistency (Cronbach's α), test-retest reliability (intraclass correlation coefficient, ICC), and construct validity were analysed. Results: The Italian VSQOL Index demonstrated excellent internal consistency, with Cronbach's α ranging from 0.89 to 0.95 across its domains, and high test-retest reliability, indicated by an ICC ranging from 0.78 to 0.92 among the domains. Significant correlations with PANQOL, SF-36, and DASS-21 scores confirmed convergent validity. Patients received the questionnaire positively, with no major comprehension issues reported during cognitive debriefing. Conclusions: The Italian VSQOL Index is a valid and reliable instrument for assessing HRQoL in Italian-speaking VS patients. Its application in clinical practice and research will enhance the evaluation of disease impact and treatment outcomes within this population.
