Depression inventory for maintenance hemodialysis patients: a cross-cultural adaptation and psychometric evaluation in Turkey.
Article in BMC nephrology, 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
backgroundThere is a clear need for more effective screening tools for patients undergoing hemodialysis, especially considering the wide variation in depression screening options and the lack of a gold standard assessment tool for this specific population. This study aims to examine the validity and reliability of the Turkish version of the Depression Inventory for Maintenance Hemodialysis Patients (DI-MHD).
methodsThis was a methodological study of the translation, cultural adaptation, and psychometric validation of the DI-MHD. Two hundred eighty-three patients from two hemodialysis units in Turkey were recruited for the study using convenience sampling. The following data were collected from the participants: descriptive characteristics, DI-MHD scores, Beck Depression Inventory (BDI) scores, and inflammatory biomarkers. The BDI was used as a reference instrument to evaluate the concurrent validity of the DI-MHD. Exploratory and confirmatory factor analyses were implemented to test the construct validity. The test‒retest method was used to test the reliability and consistency of the scale over time. IBM SPSS version 22.0 and AMOS 24.0 were used for analysis.
resultsExploratory factor analysis revealed a dominant single factor explaining 37.21% of the total variance (extracted variance = 33.52%). Although confirmatory factor analysis demonstrated acceptable fit for the correlated four-factor and second-order models, high latent factor correlations (φ = 0.677-1.052) and strong higher-order loadings (0.708-1.041) indicated limited discriminant validity among dimensions. Therefore, the one-factor model was retained as the most parsimonious and theoretically coherent solution.
conclusionThe Turkish version of the DI-MHD is a valid and reliable tool that can be used to evaluate and classify the depression levels of patients in hemodialysis units. CLINICAL
