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
objectiveThe prevalence of COVID-19-related posttraumatic stress disorder (PTSD), depression, and insomnia remains high in Chinese adolescents. Existing research suggests strong links between them and the influence of internet addiction (IA) on their development. This study therefore examined a longitudinal network of these psychological symptoms and explored the influence of IA on them.
methodAnalyses included 811 adolescents (
resultsSuicidal ideation at T1 had the strongest predictive effect on other symptoms at T2. Insomnia had the strongest bridging effect, sustaining the coactivation of depression and PTSD symptoms. The similarity between symptom networks across different IA groups was low. However, hyperarousal was strongly predicted by other symptoms in both high and low-level IA groups, respectively.
conclusionsFindings emphasize the important roles of suicidal ideation and insomnia in the network of PTSD symptoms, depressive symptoms, and insomnia in adolescents. This may make these symptoms a priority to be considered in interventions. Among adolescents with different levels of IA, the most central symptom varies, suggesting that intervention priorities should vary in groups with different levels of IA.
