Differentiating biomarker features and familial characteristics of B-SNIP psychosis Biotypes.
Article in Translational psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
Idiopathic psychosis shows considerable biological heterogeneity across cases. The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) used psychosis-relevant biomarkers to identify psychosis Biotypes, which will aid etiological and targeted treatment investigations. Here, our previous approach (Clementz et al. 2022) is updated, which supports the development of an efficient psychosis Biotype diagnostic procedure called ADEPT. Psychosis probands (n = 1907), their first-degree biological relatives (n = 705), and healthy participants (n = 895) completed a biomarker battery composed of cognitive performance, saccades, and auditory EEG/ERP measurements. EEG and ERP quantifications were modified from previous Biotypes iterations. Multivariate integration using multiple approaches reduced biomarker outcomes to 11 "bio-factors." Twenty-four different approaches indicated bio-factor data among probands were best described by three subgroups. Numerical taxonomy with k-means clustering yielded psychosis Biotypes; Rand Indices evaluated individual-case consistency of Biotype assignments. Psychosis subgroups, their non-psychotic first-degree relatives, and healthy individuals were compared across bio-factors. The three psychosis Biotypes differed significantly on all 11 bio-factors, especially prominent for general cognition, antisaccades, ERP magnitude, and intrinsic neural activity. Rand Indices showed excellent individual-case consistency of Biotype membership when samples included more than 1000 subjects. Canonical discriminant analysis described composite bio-factors that simplified group comparisons: "Pattern-2" (high antisaccade errors, low BACS, high ongoing EEG) captured Biotype-2, "Pattern-1" (low ERP amplitudes, low intrinsic EEG) captured Biotype-1, and "Pattern-3" (low frontal P3 complex, accentuated S2 ERP, faster saccadic reaction times) captured Biotype-3. First-degree relatives had patterns like their proband for general cognition, antisaccades, ERP magnitudes, and intrinsic brain activity. These outcomes refine and extend operations for characterizing biologically distinct psychosis Biotypes. They also show that over 1000 observations are useful for achieving consistent individual-case diagnostic assignments. First-degree relative data implicate specific bio-factors as familial within idiopathic psychosis which may inform genetic studies.
