Outcome of Surgery for Chronic Achilles Tendinopathy
Bibliographic record
Abstract
Achilles tendinopathy is often treated surgically after failure of nonoperative management, but results are not uniformly excellent. We critically assessed the methods of 26 studies that reported surgical outcomes of patients with this condition. Using 10 previously published criteria, and blinded to study outcomes, we derived a "methodology score" (0 to 100) for each study. This score was highly reproducible (r = 0.99, P < 0.01). Scores were generally low concerning the type of study, subject selection process, and outcome measures, which indicates methods deficiency in the way the study was designed, performed, and analyzed. We found a negative correlation between reported success rate and overall methods scores (r = -0.53, P < 0.01), and a positive correlation between year of publication and overall methods score (r = 0.70, P < 0.01). Study methods may influence reported surgical outcome, and we suggest guidelines for improving study design in this area of clinical research. We acknowledge that study methods have improved over the course of the past 20 years.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
