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

backgroundPosttraumatic stress disorder (PTSD) symptoms are among the most prevalent mental health sequelae in children and adolescents following earthquakes. A recently introduced metric under network theories of psychopathology, network temperature, quantifies the global stability of a symptom network.

methodsTo examine the developmental trajectory of network temperature in children and adolescents after earthquakes, we established eight prospective cohorts (2-4 waves per cohort; total

resultsPTSD symptom network temperatures decreased across all eight cohorts. In the early post-Wenchuan period, adolescents declined more slowly than children. Across earthquakes, the early-period decline in children was faster after the Wenchuan earthquake than after the Yaan earthquake; for adolescents, the early-period decline rate followed the order Wenchuan < Jiuzhaigou < Yaan. Across post-earthquake periods, Wenchuan adolescents declined more slowly in the early period than in the middle/late period, whereas Yaan adolescents declined faster in the early period than in the middle period.

conclusionsAcross all earthquake types and post-earthquake periods, the PTSD symptom network system became increasingly stable and resistant to change. These findings underscore the necessity of early intervention alongside efforts to prevent deterioration. However, the rate of this decline varied by sample (children versus adolescents), earthquake, and post-earthquake period. Clinically, this calls for intervention strategies that are adjusted according to these factors.
