Analyzing transdiagnostic internalizing symptoms in a global sample of trauma-exposed children using pooled individual participant data: a latent transition analysis.

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
backgroundChildren often experience both posttraumatic stress (PTS) and depression after potentially traumatic events (PTEs). Latent class analyses (LCAs) identify subgroups with different co-occurring symptoms, but little is known about what predicts transitions between these symptom classes over time. Analyzing these transitions could reveal factors that influence the shift to classes with fewer internalizing symptoms.
methodsUsing harmonized individual participant data (n = 787) from nine studies (United States, United Kingdom, Australia, and Switzerland) included in the Prospective studies of Acute Child Trauma and Recovery Data Archive (PACT/R), internalizing symptom classes (using PTS and depression items) were identified using LCAs for T1 (0-2 months posttrauma) and T2 (3-15 months posttrauma) separately. Latent transition analysis was used to examine predictors of transitions across symptom classes over time. Included predictors were age, gender, minority status, and trauma type.
resultsFive classes were identified at both time points: 'low internalizing' class (T1: 20%; T2: 40%), 'low PTS/moderate-high depression' class (T1: 20%; T2: 27%), 'moderate internalizing' class (T1: 25%; T2: 12%), 'moderate PTS/high depression' class (T1: 17%, T2: 14%), and 'high internalizing' class (T1: 16%, T2: 6%). 'Low internalizing' was the most common and stable response (87% stayed in this class). At both time points, 40% of all children were classified into either a 'low PTS/moderate-high depression' class or a 'moderate PTS/high depression' class. Children belonging to minority groups in their country of residence and children exposed to interpersonal PTEs were less likely to transition from the 'high internalizing' class to lower symptom classes.
conclusionsMost children show low PTS and depression symptoms after PTEs. When symptoms do develop, they usually involve both high depression and PTS, rather than high PTS with low depression. This underscores the importance of assessing both conditions and developing interventions that target multiple disorders. Minority children exposed to interpersonal trauma require special focus in research and treatment.
