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
objectiveThe goal of this study was to examine the prevalence of vitamin D insufficiency and deficiency among urban African-American (AA) youth with asthma compared with control subjects without asthma. STUDY
designA cross-sectional case-control study was conducted at an urban pediatric medical center. Total 25-hydroxyvitamin D insufficiency (<30 ng/mL) and deficiency (<20 ng/mL) were assessed in urban self-reported AA patients, aged 6 to 20 years, with (n = 92) and without (n = 21) physician-diagnosed asthma.
resultsBlood samples were available for 85 (92%) cases. The prevalence of vitamin D insufficiency and deficiency were significantly greater among cases than control subjects (73/85 [86%] vs 4/21 [19%], adjusted odds ratio = 42 [95% confidence interval: 4.4 to 399] for insufficiency and 46/85 [54%] vs 1/21 [5%], adjusted odds ratio = 20 [95% confidence interval: 1.4 to 272] for deficiency).
conclusionsMost of this sample of urban AA youth with persistent asthma were vitamin D deficient or insufficient. Given the emerging associations between low vitamin D levels and asthma, strong consideration should be given to routine vitamin D testing in urban AA youth, particularly those with asthma.
