Psychometric properties of the Croatian version of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25).
Observational study in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled it.
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
purposeThe purpose of the study was to translate, adapt and validate the Croatian version of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) in participants with visual impairment. This study also aims at evaluating the relationship between visual impairment and health-related quality of life (HRQoL).
methodsThe prospective observational study was conducted at the University Hospital Centre Zagreb, Department of Ophthalmology. The sample consisted of 175 patients with four chronic ocular diseases: cataract, glaucoma, diabetic retinopathy and age-related macular degeneration. The translation of the NEI VFQ-25 to Croatian was conducted following the standardised procedure. All participants underwent an ophthalmological examination and completed the NEI VFQ-25 and the Medical Outcomes Study Short Form-36 Questionnaire (SF-36). In order to assess the psychometric properties of the NEI VFQ-25, we calculated Cronbach's α coefficient, intraclass correlation coefficient (ICC), convergent and discriminant validity, as well as criterion and concurrent validity.
resultsResults show high internal consistency (Cronbach α range 0.739-0.932) and high test-retest reliability (ICC 0.876-0.975) for all subscales. None of the items had failed either convergent or discriminant validity. Moderate to high Spearman's rho coefficients of correlations were found between best corrected visual acuity and eight subscales in the NEI VFQ-25 (0.430 < ρ < 0.631). Moderate correlations were found between comparable domains in the NEI VFQ-25 and in the SF-36 questionnaire (p < 0.01).
conclusionThe Croatian version of the NEI VFQ-25 has very good psychometric properties and can be a useful instrument for assessing vision-related quality of life in Croatian population with chronic ophthalmic diseases.
