Abstract
Our objectives were to determine how frequently people living with HIV (PLHIV) in Ontario experience a non-retention episode, and associated individual, provider, and healthcare system factors. Using administrative, population-level data, we followed PLHIV from their first visit with an HIV-experienced provider until first non-retention episode (365 days without HIV care), death, or loss-to-follow-up. Kaplan-Meier curves, logrank tests, and Cox proportional hazards models were used to evaluate time-to-first non-retention episode. 15,242 PLHIV entered care between 2000 and 2018. The probability of non-retention at 3, 6 and 10 years was 21%, 41% and 58%, respectively. Non-retention was less likely for individuals who had previously accessed mental healthcare or public drug insurance, were an immigrant or refugee, or initiated care with an HIV-experienced or primary care provider. Many PLHIV in Ontario have not received care within recommended timeframes. Practice and policy improvements should focus on PLHIV with characteristics associated with non-retention.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
