Serum 25 hydroxy vitamin D insufficiency associated with bronchial asthma in Lucknow, India.

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
objectivesTo assess the association between serum 25 hydroxy vitamin D levels and asthma and its control in Indian children.
methodsThis was a prospective case-control study conducted in tertiary care hospital. Cases of asthma and healthy age-matched controls were included, aged 1-15 y, who had not received any vitamin D supplementation in the last year and had no other co-morbidity, after obtaining written informed parental consent. 25 hydroxy vitamin D insufficiency was taken below level of ≤ 30 ng/mL.
resultsFifty asthmatics and 25 age-matched controls were recruited from August 2011-July 2012. 25 hydroxy vitamin D insufficiency was associated with occurrence of asthma (OR = 13.5; 95 % CI = 4.25-42.85: p = 0.000). With decreasing level of asthma control there was increasing strength of association with 25 hydroxy vitamin D insufficiency [χ (2) for trend = 24.96 (p = 0.000)].
conclusions25 hydroxy vitamin D insufficiency is associated with bronchial asthma as well as its level of control.
