Abstract
We thank the authors for writing this letter and for stating that “the conclusion is objective and fair.”1 We also appreciate the opportunity to further reinforce the validity of our study. Regarding pain intensity encompassing multiple dimensions, we acknowledge that pain is a multifaceted experience that can be assessed in several ways. However, one of the most common primary outcomes in low back pain research is pain intensity, typically assessed by the 0 to 10 numerical pain rating scale with reference to the previous week.2,3 We deliberately have not included additional pain intensity outcomes to minimize multiple comparison tests. The more tests you perform, the higher the chance of obtaining at least 1 statistically significant—and clinically meaningless—result by chance. This can lead to false positives, where you incorrectly conclude that an effect was observed. We did, however, include function as a coprimary outcome to provide a more comprehensive assessment. We agree that we could have presented the overall group × time interaction in the results section. However, we opted to focus on mean differences and confidence intervals, which are much more comprehensive for clinicians. For those interested in the statistical analysis output, the results of the interaction effect are available online.4

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.
