Where is mania in the meta-structure of psychopathology?
Article in Psychological medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe nosology of mania has long been a conundrum. Prior studies have alternately concluded that it is an internalizing disorder, a thought disorder, or a unique condition. Unfortunately, nearly all existing studies assessed symptoms cross-sectionally. This is problematic for syndromes that follow a more episodic course, such as mania. Here, we test whether including a history of episodes, not simply current symptoms, can help resolve the placement of mania in the meta-structure of psychopathology.

resultsFor depression and psychosis, current and past markers were congruent in loading onto internalizing and thought disorder factors, respectively. However, current and past markers of mania diverged: current mania was most strongly related to the thought disorder dimension, whereas past mania formed an independent factor. Classic correlates of mania - including family history, genetic risk, and neuropsychological function - were associated only with the history of mania dimension.
conclusionsIncluding illness course in structural models of psychopathology suggests that mania is distinguished from internalizing and thought disorder factors, whereas assessments of current symptoms place it with psychosis. These findings require independent validation, but if replicated, they would support a separate spectrum of mania defined by the occurrence of episodes across the lifetime.
