Prognosis of COVID-19 infection among opium users in Iran,2020: a hospital-based study
Bibliographic record
Abstract
Introduction Since Iran has the highest opioid consumption in the world and the literature surrounding the association of COVID-19 with opioid consumption is still insufficient, in this study, we aimed to present the individual, clinical, and outcome characteristics of patients with COVID-19 disease who had a history of opium use.Methods In this cross-sectional study, 1,985 patients, with a history of opium consumption, who were admitted to hospital because of COVID-19 disease were evaluated. Data were obtained from February 24, 2020 to June 21 2021, using the Medical Care Monitoring Center (MCMC) system of Shiraz University of Medical Sciences located in the province of Fars.Results The mean age of patients was 57.3 ± 17.1 years. The most common symptoms of COVID-19 disease were loss of consciousness (77.4%). 25% of patients had underlying diseases, the most common of which were cardiovascular disease (21.4%) and hypertension (21.2%). Out of 1,985 patients 251 (12.6%) died due to COVID-19. Multiple logistic regression showed that age, gender, having underlying diseases and high-resolution (HRCT) of lung are associated with mortality.Conclusion Our results showed, age 40–59 years, male gender, presence of underlying disease(s) and HRCT of the lung with finding, are correlated to the mortality of COVID-19 hospitalized patients with a history of opium consumption.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
