Abstract

fetched live from OpenAlex

Clinical trials are essential for establishing the benefits and harms of various treatments. Among the various trial designs, superiority trials aim to establish the superiority of one treatment over another, while noninferiority trials demonstrate that a new treatment is not inferior to an established one while minimizing harms or patient burdens. In recent years, noninferiority trials have gained prominence. This mini-review explores noninferiority trials, focusing on challenges in their interpretation. Ultimately, we argue that the focus should be on the results from trials rather than their design, as clinicians and other stakeholders primarily seek evidence that helps patients and clinicians in trade-offs of the benefits and harms and burdens of treatment options. PATIENT SUMMARY: Our mini-review shows that looking at the overall treatment benefits and harms in noninferiority trials is better than focusing on the trial design. This approach would help patients and clinicians to better understand trial results and their implications.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
