Abstract
Background: In acute COVID-19, plasma D-Dimer is a useful biomarker and venous thromboembolism (VTE) is common. However, it is less clear whether this is the case during long-term recovery. Objectives: To report D-Dimer values and incidence of new VTE ≥90 days following COVID-19. Methods: In British Columbia (BC), patients supported at the Post-COVID-19 Recovery Clinics underwent routine investigations including D-Dimer as part of a learning health system. Among patients with a positive D-Dimer (≥500ng/mL) test 90–180 days following COVID-19 symptom onset, we performed a retrospective chart review to determine whether imaging for VTE was done. Results: There were 806 patients reviewed. Of these, 252 (30.3%) had a positive D-Dimer. Imaging was pursued in 56 (6.9%) and 9 (1.1%) were diagnosed with new VTE. Interpretation: At ≥90 days post COVID-19, D-Dimer is often positive, but it is relatively rare to diagnose new VTE.

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
