Abstract
OBJECTIVE: Circular RNA (circRNA) molecules may play a significant role in the pathogenesis of psychiatric disorders by regulating synaptic gene expression. This study aimed to evaluate the relationship between the peripheral expression levels of three circRNA molecules (chr3_196488683, chr5_69175537, and hsa_circ_0084021) and clinical characteristics, specifically behavioral phenotypes related to self-harm and harm to others, in individuals diagnosed with schizophrenia and schizoaffective disorder. METHODS: The study included 104 patients aged 18–65 diagnosed with schizophrenia or schizoaffective disorder. RNA was isolated from peripheral blood, and circRNA molecules were identified using RNA sequencing techniques. Clinical status was assessed using the Positive and Negative Syndrome Scale, Clinical Global Impressions Scale, Global Assessment of Functioning, Calgary Depression Scale for Schizophrenia, Beck Anxiety Inventory, Beck Scale for Suicide Ideation, and Suicide Probability Scale. The relationship between concurrent circRNA levels and clinical features was investigated. RESULTS: A significant positive correlation was observed among the circRNAs (p<0.001). Apart from a weak positive correlation between chr3_196488683 and the Beck Anxiety Inventory score (r=0.213, p=0.03), no significant relationship was found between clinical scales and circRNAs. No significant difference was detected between groups regarding suicidal behavior. However, mean levels of all circRNAs were found to be statistically significantly higher in the group with self-injurious behavior (chr3_196488683, p=0.036; chr5_69175537, p=0.001; hsa_circ_0084021, p=0.045). Similarly, levels of chr3_196488683 and chr5_69175537 were significantly higher in the group with homicidal behavior (p<0.001). CONCLUSION: The findings suggest that peripheral circRNA levels may be associated with anxiety and behavioral risk profiles involving harm to self or others, indicating their potential value as biomarkers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
