Abstract

fetched live from OpenAlex

UNLABELLED: To examine the relapse rate achievable in a real-life early psychosis treatment service. METHOD: A 2-year longitudinal cohort study of consecutive admissions to an early psychosis programme which served the entire population in a catchment area. The primary outcome measure was relapse. RESULTS: One hundred and forty-eight consecutive consenting admissions were recruited, 124 (83.8%) of whom were followed for 1 year and 116 (78.4%) for 2 years. Relapse was assessed by clinicians using structured criteria. The 2-year relapse rate among subjects with complete data collection was 34/95 (35.7%, 95% CI 26.2-46.3). A Kaplan-Meier life table censoring subjects lost to follow-up yielded a comparable estimate of the proportion not relapsing: 68% (95% CI 58-76%). CONCLUSION: These estimates compare favourably with a published range of 2-year relapse from 55% to 70% in the older literature and are comparable with the results in recent clinical trials.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
