The natural history of chronic painful peripheral neuropathy in a community diabetes population
Bibliographic record
Abstract
AIMS: To examine the natural history of chronic painful diabetic neuropathy (CPDN). METHODS: A cross-sectional study of 350 people with diabetes was performed during 1998-1999 to assess the prevalence of CPDN in the community. Fifty-six patients with CPDN were identified and were followed up an average of 5 years later. RESULTS: From the original cohort, 12 patients had died and 14 had moved away or were unable to participate in the follow-up study. Thus 30 patients with CPDN [21 male, mean (SD) age 68.6 years (9.4), mean (SD) duration of diabetes 15.4 years (8.7)] were re-assessed. Seven (23%) had been pain free for at least 12 months and 23 continued to report neuropathic pain of similar quality and severity [total McGill Pain Questionnaire Score median (interquartile range) at follow-up 22 (16-39) vs. 20 (16-33) at baseline, P = 0.3; mean (SD) visual analogue scale (VAS) score for pain over the preceding 24 h 5.3 cm (2.9) vs. 4.6 cm (2.5) at baseline, P = 0.1]. Only 65% had ever received treatment for CPDN despite 96% (22/23) reporting pain to their physician; 43.5% had received antidepressants, 17.4% anticonvulsants, 39% opiates and 30% had tried complementary therapies. CONCLUSIONS: The neuropathic pain of CPDN can resolve completely over time in a minority (23%). In those in whom painful neuropathic symptoms had persisted over 5 years, no significant improvement in pain intensity was observed. Despite the improvement in treatment modalities for chronic pain in recent years, patients with CPDN continue to be inadequately treated.

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.
