Abstract
For the purpose of comparing the efficacy and safety of a Similar Biotherapeutic Product (SBP) to a Reference Biotherapeutic Product (RBP), the "Guidelines on Evaluation of Similar Biotherapeutic Products (SBPs)" issued by the World Health Organisation (WHO), states that equivalence or non-inferiority studies may be acceptable. While in principle, equivalence trials are preferred, non-inferiority trials may be considered if appropriately justified, such as for a medicinal product with a wide safety margin. However, the statistical issues involved in the design, conduct, analysis and interpretation of equivalence and non-inferiority trials are complex and subtle, and require that all aspects of these trials be given careful consideration. These issues are important in order to ensure that equivalence and non-inferiority trials provide valid data that are necessary to draw reliable conclusions regarding the clinical similarity of an SBP to an RBP.

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 it
