Psychometric Validation of the Spanish Version of the Sheffield Preference-Based Venous Leg Ulcer Questionnaire (SPVU-5D) in Patients With Venous Leg Ulcers.
Article in International wound journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Venous leg ulcers are a common manifestation of chronic venous disease and are associated with substantial morbidity and impaired health-related quality of life (HRQoL). Patient-reported outcome measures are essential for capturing the patient perspective of disease burden and treatment outcomes in wound care management. The Sheffield Preference-based Venous Ulcer questionnaire (SPVU-5D) is a concise preference-based instrument designed to assess the quality of life in individuals with venous leg ulcers and to support health-economic evaluation. However, its measurement properties have not been extensively examined in different linguistic contexts. This study aimed to evaluate the psychometric properties of the Spanish version of the SPVU-5D in patients with venous leg ulcers. A methodological validation study was conducted involving 132 patients (264 observations from pre- and post-treatment assessments) with a mean age of 63.76 ± 10.02 years. Cross-cultural adaptation followed the established guidelines for translation and cultural equivalence. Content validity was assessed using Aiken's V coefficient. Structural validity and reliability were examined using multilevel confirmatory factor analysis and measurement performance was further evaluated using a multilevel graded response model based on item response theory. Floor and ceiling effects, minimum detectable change and convergent validity with the RESVECH 2.0 clinical scale were also evaluated. Confirmatory factor analysis supported a unidimensional structure with excellent fit indices and satisfactory internal consistency. Item response theory analyses showed high item discrimination and well-distributed difficulty thresholds for the items. The floor and ceiling effects were minimal, indicating adequate sensitivity across the latent trait continuum. The Spanish version of the SPVU-5D demonstrates satisfactory validity, reliability and measurement precision and represents a useful instrument for assessing the health-related quality of life in patients with venous leg ulcers.
