Correlation of quality of life scores to clinical outcome of lumbar epidural steroids in chronic low back pain
Bibliographic record
Abstract
CONTEXT AND AIM: The assessment of severity of low back pain includes subjective questionnaires to quantify the impact on routine life. The objective of current study was to correlate various quality of life (QOL) scores to the clinical outcome measured as improvement in Visual Analog Score (VAS) after interventional treatment. SUBJECTS AND METHODS: Fifty-one consecutive chronic low backache patients were assessed for pain intensity using VAS, revised Oswestry Disability Index (ODI), Quebec's, Roland-Morris disability questionnaire (RMDQ), and depression score at presentation. All subjects received interventional therapy complemented with physiotherapy; changes in scores were evaluated at 2 weekly intervals till 12 weeks. TYPE OF STUDY: Prospective, observational, cohort study. RESULTS: < 0.001). The Pearson correlation of VAS with rest of the scores showed that all variables correlate well with VAS at various time periods till 3 months. However, the best outcome predictor for VAS in QOL scores was Oswestry score as well as depression score which had an additive predictive effect. Among the QOL scores best intercorrelation was found with ODI and RMDQ scores at baseline as well as at all treatment follow-ups. INTERPRETATION AND CONCLUSION: ODI and depression score closely parallel trends of reduction in VAS indicating that these scores may be the best outcome predictor after interventional treatment of pain. Among QOL scores ODI and RMDQ evaluated in the current study record comparable degree of physical incapacity; the exception is Quebec's score.

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.
