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

backgroundDifferences in subjective stress perception and acute response of the hypothalamic-pituitary-adrenal axis have been reported in internet gaming disorder (IGD). The present study aimed to further investigate alterations in diurnal profiles of the endocrine stress response system in IGD compared to healthy controls (HCs).

methodsThe diurnal course of endocrine markers (salivary cortisol and α-amylase) was investigated in a clinical sample of n = 29 adolescents with IGD compared to n = 26 HC. Further, the effect of unrestricted gaming versus restricted gaming was examined within the IGD group.

resultsNo significant differences in salivary cortisol and α-amylase were observed comparing adolescents with IGD and HC. In addition, in the IGD group, there were no significant differences in salivary cortisol and α-amylase between conditions of unrestricted gaming versus restricted gaming. Compared to the HC group, the IGD group showed a significantly higher body mass index.

conclusionsOur results indicate no alteration in diurnal profiles of the endocrine stress response in IGD.
