The efficacy of vitamin D supplementation in the management of childhood asthma: a systematic review and meta-analysis.
Synthesis in Frontiers in nutrition, 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
Background: Childhood asthma is a major public health concern. Current evidence regarding vitamin D supplementation in childhood asthma remains inconsistent, particularly with respect to pulmonary function. This study comprehensively evaluates the role of vitamin D supplementation in childhood asthma, with a particular focus on lung function. Method: PubMed, EMBASE, Web of Science, and the Cochrane Library were searched through October 31, 2025 for RCTs. Data were extracted and analyzed using FEV1 (%) as the primary outcome measure, and FVC (%), FEV1/FVC, PEF, FeNO, cACT, and IgE as secondary outcome measures. Results: Twelve RCTs ( Conclusion: Vitamin D supplementation showed no overall benefit for lung function, IgE levels, FeNO, or cACT scores in children with asthma.
