Alignment of Lived Experience Questions with the Medical Literature in Bipolar Disorder: A Topic Modelling Approach: Adéquation entre les questions relatives à l'expérience vécue et la littérature médicale concernant le trouble bipolaire : Une approche de modélisation de sujets.
Article in Canadian journal of psychiatry. Revue canadienne de psychiatrie, 2026. 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
ObjectiveThe priorities of people with mental health challenges should be reflected in the research conducted on their behalf. Quantifying alignment of priorities with the unmet needs of people with lived experience is challenging, and to our knowledge, such alignment has not been extensively studied in bipolar disorder (BD). Natural language processing approaches comparing common topics derived from public forums to those of biomedical research could help in identifying topics that are underaddressed.MethodsWe contrasted 5 years of lived experience questions posed during a Collaborative RESearch Team to study psychosocial issues in Bipolar Disorder (CREST.BD) "Ask Me Anything" (AMA) event hosted via Reddit (2019-2023) with topics labelled from abstracts extracted from PubMed with the search term BD during the same period. We applied topic modelling using BERTopic to identify dominant themes within each corpus and compared their semantic similarity using vector-based cosine similarity analyses.ResultsThe Reddit AMA data included 6159 comments, and the medical literature from this period included 9188 abstracts. Topic modelling and similarity analyses indicated that shared and frequent topics in both corpuses were sleep, BD medication safety in pregnancy, and lithium treatment. Topics with comparatively higher frequency in the Reddit forums than in medical research included BD misdiagnosis, marijuana and BD, and coping with daily challenges.DiscussionNotwithstanding limitations, comparing a corpus of lived experience questions with contemporaneous medical literature revealed areas of overlap, but some lived experience queries were not well covered in the biomedical literature. Natural language processing of public forums may facilitate identifying unmet priorities in BD.
