CROSS-CULTURAL ADAPTATION OF THE LIVER DISEASE UNDERNUTRITION SCREENING TOOL TO BRAZILIAN PORTUGUESE.

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
backgroundChronic liver diseases represent a relevant public health problem, and undernutrition is one of their most frequent complications, being associated with higher morbidity and mortality in patients with cirrhosis. Early identification of undernutrition risk in outpatients with liver disease is fundamental; however, there is no nutritional screening tool culturally adapted for this population in Brazil. The Liver Disease Undernutrition Screening Tool (LDUST) is a simple and validated instrument for this purpose.
objectiveThe objective of this study was to perform the cross-cultural adaptation of the LDUST instrument into Brazilian Portuguese.
methodsThe cross-cultural adaptation process followed the methodology of Beaton et al. (2000). The original tool in English was translated into Brazilian Portuguese by two independent translators, synthesized, and back-translated by two native English translators. The multidisciplinary committee evaluated semantic, idiomatic, experiential, and conceptual equivalences, consolidating the pre-final version named Triagem de Desnutrição em Pacientes com Doença Hepática (TriDH). This version was then electronically administered to healthcare professionals from different regions of Brazil. Internal reliability was analyzed using Cronbach's alpha, adopting a minimum acceptable value of 0.8. The study was approved by the Research Ethics Committee of the Hospital de Clínicas de Porto Alegre, and all participants signed the Informed Consent Form.
resultsIn the pretest, the TriDH was administered to 38 healthcare professionals. It was considered easy to understand. The questionnaire presented excellent internal consistency (Cronbach's alpha = 0.88), with all eight items exhibiting values greater than 0.8.
conclusionThe LDUST was adapted into Portuguese, originating the TriDH. This Brazilian version demonstrated high internal consistency and adequate understanding among healthcare professionals.
