Prevalence of vitamin D deficiency and insufficiency among 460,537 children in 825 hospitals from 18 provinces in mainland China.
Observational study in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 2 of them syntheses that pooled it.
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
This study was conducted to estimate the 25-hydroxyvitamin D (25 (OH)D) levels and explore factors related to vitamin D deficiency/insufficiency. This was a multicenter, hospital-based, cross-sectional observational study. Children admitted to hospitals for health examination were included for vitamin D measurement and the 25(OH)D concentration results were categorized into 3 groups: deficiency (<30 nmol/L), insufficiency (30-50 nmol/L), and sufficiency (>50 nmol/L). Four lakh sixty thousand five hundred thirty-seven children in 825 hospitals from 18 provinces participated in this study. The prevalence of vitamin D deficiency, insufficiency, and sufficiency were 6.69%, 15.92%, and 77.39%, respectively. Vitamin D deficiency was the most severe in the central region, followed by the north, and southwest regions; however, data for the western region were lacking.Logistic regression showed that vitamin D status was worse in girls, newborns, and those visiting the hospital in the winter. In conclusion, the prevalence of vitamin D deficiency is high among Chinese children and adolescents. Studies on population estimates, cost-effective screening strategies, and interventions for high-risk cases are needed.
