Cross-cultural adaptation of the upper limb functional index in Arabic.

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 AND
aimThe upper limb functional index (ULFI) is a widely used self-reported outcome measure questionnaire with robust psychometric properties to assess the upper limb musculoskeletal disorders (UL-MSDs). This study aimed to adapt the ULFI cross-culturally in Arabic (ULFI-Ar) and to examine its face validity, content validity, internal consistency, criterion validity, and interpretability.
methodsIn this observational cross-sectional study, the English version of ULFI was cross-culturally adapted to the Arabic language through double forward and backward translations, following the recommended guidelines. Interviews with participants and reviews by experts were used to assess the face and content validity of the prefinal version of ULFI-Ar. Internal consistency was determined by Cronbach's alpha coefficient (a). Criterion validity was analyzed by correlating the ULFI-Ar with the Arabic version of the Disabilities of the Arm, Shoulder, and Hand (DASH-Arabic) using Pearson's correlation coefficients.
resultsA total of 54 participants reported no major language barriers or difficulties in completing the ULFI-Ar. The participants' interview demonstrated adequate face validity. The review by experts showed that the content validity was excellent (content validity index = 0.81 - 1.00 for each item and 0.96 for the scale). The ULFI-Ar showed high internal consistency (a = 0.88). For criterion validity, there was strong correlation with the DASH-Arabic (r = -0.802, p < 0.0001) and moderate correlation with NPRS-Arabic (r = -0.502, p < 0.0001).
conclusionsThe ULFI-Ar was easy to complete with no linguistic difficulties. The results demonstrate the suitability of using the ULFI-AR for Arabic-speaking patients with UL-MSD.
