Reliability and Validation of the Vietnamese Utian Quality-of-Life Scale in Postmenopausal Women.
Article in International journal of environmental research and public health, 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
The absence of a culturally adapted instrument to assess menopause-specific quality of life in Vietnamese women limits both clinical practice and research in this population. This study aimed to translate, culturally adapt, and psychometrically validate the Vietnamese version of the Utian Quality of Life (VN-UQOL) Scale. A cross-sectional design was employed with 384 community-dwelling postmenopausal women aged 46-65 years. The UQOL was translated and adapted following established guidelines, including forward-back translation, expert review, and pilot testing. Internal consistency was evaluated using Cronbach's alpha, construct validity through confirmatory factor analysis (CFA), and concurrent validity via Pearson correlations with the Vietnamese Menopause Rating Scale (VN-MRS). The VN-UQOL demonstrated excellent internal consistency, with a total scale Cronbach's alpha of 0.87 and sub-scale alphas ranging from 0.81 to 0.93. Content validity indices (I-CVI, S-CVI) were 1.0. CFA confirmed the original four-factor structure, with all factor loadings exceeding 0.50 and good model fit indices (CFI = 0.921, RMSEA = 0.072). Concurrent validity was supported by significant negative correlations between the VN-UQOL sub-scales and corresponding VN-MRS domains (
