Social cognition in bipolar I and II disorders: an updated systematic review and meta-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
objectiveIn recent years, there has been a rapid increase in reports upon social-cognition impairments in bipolar disorder. This study aimed to compare the characteristics of social cognition domains in bipolar I (BD I) and II (BD II) based on the findings to date.
methodsA systematic literature search was conducted on Web of Science and PubMed from inception to 28 August 2024. Studies with all-age-group of ICD-10, DSM-IV, DSM-IV-TR, or DSM-5 defined BD (I or II) either in a remitted or symptomatic state were included. The risk of bias was measured using the Newcastle-Ottawa Scale, and the quality of the sources was evaluated using GRADE criteria. Results of the studies were measured by synthesizing Hedge's g effect sizes through a random effects meta-analytic approach.
resultsA total of 20 studies were included, covering three core domains of social cognition (theory of mind (ToM), emotion processing and attributions). There was no significant difference in ToM between BD I and BD II and in emotion processing between non-psychotic patients with BD I and BD II, and history of psychosis negatively predicted performance on emotion processing. Furthermore, BD II performed worse than BD I in attributions, with a low to moderate summary effect size.
conclusionsBD I and BD II performed similarly on ToM and emotional processing, but BD II had more impaired attributions. Future studies are encouraged to control for the influence of clinical features, to use more neuroscientific techniques, and to explore on other domains of social cognition in bipolar subtypes.
