Psychometric evaluation of the Albanian version of the Neck Disability Index in a large cohort of patients with cervical pain.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Background: The Neck Disability Index (NDI) is one of the most widely used instruments for evaluating neck pain disability. To date, no validated version has been available in Albanian. This study aimed to translate, culturally adapt, and evaluate the psychometric properties of the Albanian version of the NDI (ANDI). Methods: The ANDI was developed using a standardized forward-backward translation method. A cross-sectional study was conducted among 566 participants with neck pain. Reliability was assessed through internal consistency (Cronbach's alpha) and test-retest reliability (Intraclass Correlation Coefficient, ICC Results: The ANDI showed excellent reliability, with Cronbach's alpha values ranging from 0.981 to 0.993 and ICC Conclusion: The ANDI is a reliable, valid, and culturally adapted measure of neck disability for Albanian-speaking populations, suitable for both clinical practice and research.
