[Association of vitamin D level with asthma control and pulmonary function in asthmatic children aged 4-12 years].
Observational study in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2018. 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
objectiveTo study the association of vitamin D level with asthma control and pulmonary function in children with asthma.
methodsA total of 150 children with asthma were enrolled as observation group, and 55 healthy children were enrolled as control group. According to the level of asthma control, the children were divided into good control group, partial control group, and non-control group. Chemiluminescence microparticle immunoassay was used to measure the serum level of 25-hydroxyvitamin D [25(OH)D] for all groups. According to the level of 25(OH)D, the asthmatic children were divided into normal vitamin D group, vitamin D insufficiency group, and vitamin D deficiency group. Pulmonary function was measured for all asthmatic children.
resultsThe observation group had a significantly lower serum level of 25(OH)D than the control group (25± 7 ng/mL vs 29± 4 ng/mL; P<0.05). The normal vitamin D group had the highest asthma control rate, followed by the vitamin D insufficiency group and the vitamin D deficiency group (P<0.05). There was no significant difference in pulmonary function among the three groups (P>0.05).
conclusionsAsthmatic children have a lower serum level of 25(OH)D than healthy children. The serum level of 25(OH)D is associated with the level of asthma control and has no association with pulmonary function.
