Vitamin D levels in a paediatric population of normal weight and obese subjects.

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
backgroundVitamin D exerts pleiotropic effects and few studies are available in the Italian population.
aimAim of our study was to evaluate vitamin D status in children living in Northern Italy.
methodsWe studied vitamin D levels in a population of 113 normal weight (NW) and 444 obese (OB) children, prepubertal and pubertal. We considered vitamin D levels >20 ng/ml as normal, but also measured percentage of children with vitamin D levels higher than a cutoff of 30 ng/ml.
results68.2 % of NW children showed normal levels of vitamin D, while 31.8 % showed a clear vitamin D deficiency. Only 28.3 % showed vitamin D levels higher than 30 ng/ml. Obese children showed 55.6 % of subjects with normal levels of vitamin D and 44.4 % of subjects a status of vitamin D deficiency. Only the 18.9 % showed vitamin D levels higher than 30 ng/ml. Mean vitamin D levels in NW children (27.3 ± 1.2 ng/ml) were higher than in OB children (21.8 ± 0.6 ng/ml). No differences have been found between prepubertal and pubertal children in terms of vitamin D levels.
conclusionsOur paediatric population demonstrates a low percentage of vitamin D sufficiency. In particular, obese children show only 19 % of subjects with normal levels while almost half of this population shows a clear deficiency. Further studies are needed to support these results and to evaluate the possible metabolic consequences.
