Vitamin D deficiency in children and adolescents.

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
objectiveVitamin D deficiency is an important health problem in both developed and developing countries. Recent reports on the extraskeletal effects of vitamin D have led to increased interest in prevalence studies on states of deficiency/insufficiency of vitamin D. The aim of this study was to determine the frequency of vitamin D deficiency and insufficiency in children and adolescents residing in Ankara, Turkey and to investigate the factors associated with low vitamin D status.
methodsA total of 440 children and adolescents aged between 0 and 16 years were enrolled in this study. The subjects were divided into three groups according to their vitamin D status (deficiency ≤15 ng/mL; insufficiency: 15-20 ng/mL; sufficiency ≥20 ng/mL) and also according to their age (preschool<5 years; middle childhood: 5-10 years; adolescence: 11-16 years).
resultsOverall, 40% of the subjects were found to have 25 hydroxy vitamin D [25(OH)D] levels of less than 20 ng/mL. The levels indicated a deficiency state in 110 subjects (25%) and insufficiency - in 66 (15%). The rate of vitamin D deficiency was higher in girls, regardless of age. 25(OH)D levels correlated negatively with age (r=-0.48, p<0.001), body mass index (BMI) (r=-0.20, p=0.001) and intact parathyroid hormone (iPTH) level (r=-0.31, p=0.001). A positive correlation was observed between 25(OH)D and serum ferritin levels (r=0.15, p=0.004).
conclusionsThe high frequency of vitamin D deficiency in childhood (especially among adolescent girls) indicates a need for supplementation and nutritional support.
