Associations of serum 25-hydroxyvitamin D and vitamin D receptor polymorphisms with dengue severity in hospitalized Vietnamese children.
Article in IJID regions, 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
Objectives: To investigate the associations of serum 25-hydroxyvitamin D (25(OH)D) concentrations and vitamin D receptor (VDR) polymorphisms with dengue severity in hospitalized Vietnamese children. Methods: This cross-sectional study included 190 children aged ≤16 years with laboratory-confirmed dengue admitted to Ca Mau Obstetrics and Pediatrics Hospital, Vietnam. Disease severity was classified according to the World Health Organization 2009 criteria. Serum 25(OH)D concentrations were measured, and four VDR polymorphisms (FokI, BsmI, ApaI, and TaqI) were genotyped. Associations with severe dengue were assessed using univariable and multivariable logistic regression. Results: Thirty-two children (16.8%) had severe dengue. Median serum 25(OH)D concentrations were lower in children with severe dengue than in those with non-severe dengue (21.26 vs 26.65 ng/mL; Conclusion: Lower serum 25(OH)D concentrations were associated with severe dengue, whereas the investigated VDR polymorphisms were not. Prospective multicenter studies are needed to clarify temporality and causality.
