1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study aims to assess the relationship of serum Mg and vitamin D levels in a nationally-representative sample of Iranian adolescents.

methodsThe study participants consisted of 330 students, aged range from 10 to 18 years, consisting of an equal number of individuals with and without hypovitaminosis D. The correlation between serum 25 hydroxy vitamin D (25(OH) D) and magnesium (Mg) concentrations was determined.

resultsThe mean age of participants was 14.74 ± 2.587 years, without significant difference between those with hypovitaminosis D and those without it. The mean 25(OH) D level was 6.34 ± 1.47 ng/ml in the group with hypovitaminosis D and 39.27 ± 6.42 ng/ml in the group without it. The mean Mg level was 0.80 ± 0.23 mg/dl with lower level in the group with hypovitaminosis D than in others (0.73 ± 0.22 mg/dl vs. 0.87 ± 0.22 mg/dl, respectively) and according to t-test analysis, significant lower levels in the deficient group was observed (P = 0.0001). The linear regression analysis showed the meaningful relationship between Mg and 25(OH) D serum levels (P = 0.0001).

conclusionsOur study revealed significant associations between serum Mg and 25(OH) D levels. This finding may be of use for further studies on the prevention and management of hypovitaminosis D in children and adolescents. Further longitudinal studies shall evaluate the underlying mechanisms and the clinical significance of the current findings.
