Abstract

fetched live from OpenAlex

Clinical trials produce research that is intended to add to medical knowledge and improve the way we treat patients. Unfortunately, trials of the same condition don't always report the same outcomes, making synthesis of results from different studies challenging. A core outcome set (COS) is a condition-specific set of outcomes, which should be agreed and established as a minimum reporting standard for all clinical trials of interventions for that condition. This will ensure that the results can contribute to future data synthesis. Additionally, use of COS will minimise reporting biases by standardising the outcomes that are reported for a condition. A systematic review investigating caesarean rates in trials of induction of labour identified 157 trials with 31,085 included patients (Mishanina et al. CMAJ Canadian Medical Association Journal 2014;186:665–73). All of the trials reported rates of caesarean section but only 20 trials reported maternal mortality rates. Synthesis of the data for the rate of caesarean section gave a result with narrow confidence intervals (RR 0.88, 95% CI 0.84–0.93) but because the maternal mortality data was scarce and because this outcome is rare, the synthesis of the results gave a wide confidence interval (RR 1.00, 95% CI 0.10–9.57). Had all 157 trials reported maternal mortality as a core outcome, synthesis of these results would have been more likely to have produced a useful result that would be able to inform clinical guidelines. COS development has been driven by the COMET (Core Outcome Measures in Effectiveness Trials) initiative. One of the most important aspects of a COS is that all potential stakeholders are involved during the development, to ensure that the final set of outcomes is relevant to the people whom the interventions directly or indirectly target; not only researchers but health professionals, policy makers and most importantly patients and their relatives. It is envisaged that in the future, a COS will exist for all medical conditions. When designing a clinical trial, researchers should search the COMET database to check whether a COS exists for their condition of interest and if it does they should use the specified outcome in their trial or justify why they have chosen not to.

Teacher imitation

Not 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.
