Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

SUMMARY A hospital‐based cross‐sectional study examined 657 consecutive referrals with low back pain over two years to a district rheumatology service serving a population of about 250,000 people. Five hundred and thirty‐eight had mechanical/degenerative low back pain. The mean age was 48.6 (range 18–80 SD 15.3) years; 64% were women. Patients with radiating pain or neurological deficit (Quebec Task Force classification) were significantly more disabled (Roland disability score p<0.001) and depressed (Modified Zung score p<0.05) than those without radiating pain. Women were more impaired (p=0.02) than men but had similar disabilities (mean Roland score 11.7, range 0–24 SD 6.5). Fifty‐three per cent of patients were receiving benefits and were significantly more likely to have musculoskeletal comorbidities than those in work (p<0.025). It is concluded that the Quebec Task Force classification of low back pain impairment is a helpful descriptor and related to both physical and psychological disability and handicap in employment.

Not 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.
