[Serum levels of 25-hydroxyvitamin D in children with tic disorders].
Article in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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 examine serum 25-hydroxyvitamin D levels in children with tic disorders (TD) and to explore the relationship between vitamin D level and TD.
methodsOne hundred and thirty-two children who were diagnosed with TD between November 2016 and May 2017 were enrolled as the TD group, including 8 cases of Tourette syndrome, 32 cases of chronic TD, and 92 cases of transient TD. One hundred and forty-four healthy children served as the control group. Peripheral venous blood samples were collected from each child. Serum levels of 25-hydroxyvitamin D were measured using HPLC-MS/MS. The categories of vitamin D status based on serum 25-hydroxyvitamin D level included: normal (>30 ng/mL), insufficiency (10-30 ng/mL) and deficiency (<10 ng/mL).
resultsMean serum level of 25-hydroxyvitamin D in the TD group was significantly lower than that in the control group (P<0.01). The rate of vitamin D insufficiency or deficiency in the TD group was significantly higher than in the control group (P<0.01). Mean serum level of 25-hydroxyvitamin D in the transient tic group was higher than in the TS group (P<0.05).
conclusionsVitamin D insufficiency or deficiency might be associated with the development of TD, and the level of serum 25-hydroxyvitamin D might be related to the classification of TD.
