Psychometric appraisal of the Kurdish version of the Revised Hearing Handicap Inventory-Screening.

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
The Revised Hearing Handicap Inventory-Screening (RHHI-S) is a robust 10-item Patient-Reported Outcome Measure (PROM) that can quantify impacts of hearing loss (HL). Employing a cross-sectional study, the psychometric properties of a cross-culturally adapted Kurdish version of RHHI-S (RHHI-S-CK) were investigated. According to the degrees of HL, 168 enrollees (64.3% male; mean-age 63.1 ± 12.6 years) were divided into three subgroups; that is, mild (n = 56; 67.9% male; mean-age 60 ± 12.5 years), moderate (n = 64; 60.9% male; mean-age 64.6 ± 12.5), & moderately-severe (n = 48; 64.6% male; mean-age 63.1 ± 12.6). The internal cohesion among the items was confirmed by Cronbach's alpha (0.94). Confirmatory factor analysis recognised structural validity when a strong unidimensional factor was extracted. Convergent validity was verified (P-value < 0.001) via Spearman's correlation between the scale and a subjective correlator (visual analogue scale). A large effect size (0.88) from Kruskal-Wallis & Dunn-Bonferroni post-hoc tests established the discrimination between different degrees of HL. Lastly, intraclass correlation coefficient (ICC) proved the external reliability of the adapted version of the tool (Test-retest ICC = 0.95). RHHI-S-CK is a robust PROM that can measure the impacts of HL in adults across all age ranges. Accordingly, RHHI-S-CK augmented the clinical and academic practice of the Kurdish medical community.
