Semantic abnormalities in schizophrenia and bipolar disorder: A natural language processing approach.
Article in Science progress. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionThe diagnostic boundaries between schizophrenia and bipolar disorder are controversial due to the ambiguity of psychiatric nosology. From this perspective, it is noteworthy that formal thought disorder has historically been considered pathognomonic of schizophrenia. Given that human thought is partially based on language, we can hypothesize that alterations in language may help differentiate between schizophrenia and bipolar disorder.
methodIn this exploratory study, we employed natural language processing techniques to identify differences in language abnormalities between patients with schizophrenia and bipolar disorder. The KoBERT and KoGPT language models were used to determine sentence acceptability, assessing how natural and therefore acceptable a given sentence is to the general population. In addition, semantic word networks were constructed for each group, and network measures were compared.
resultsPatients with schizophrenia or bipolar disorder used less acceptable sentences than controls.
conclusionsPatients with schizophrenia and bipolar disorder showed significant differences in sentence acceptability as calculated by the language model, as well as in the network metrics estimated by semantic network analysis. Thus, language abnormalities may represent surrogate markers of thought disorders and help differentiate between schizophrenia and bipolar disorder.
