Abstract

fetched live from OpenAlex

OBJECTIVE: Ethical guidelines are designed to ensure benefits, protection and respect of participants in clinical research. Clinical trials must now be registered on open-access databases and provide details on ethical considerations. This systematic survey aimed to determine the extent to which recently registered clinical trials report the use of standard of care and post-trial obligations in trial registries, and whether trial characteristics vary according to setting. METHODS: We selected global randomized trials registered on http://www.clinicaltrials.gov and http://www.controlled-trials.com. We searched for intervention trials of HIV/AIDS, malaria, and tuberculosis from 9 October 2004, the date of the most recent version of the Helsinki Declaration, to 10 April 2007. RESULTS: We collected data from 312 trials. Fifty-eight percent (58%, 95% CI = 53 to 64) of trial protocols report informed consent. Fifty-eight percent (58%, 95% CI = 53 to 64) of trials report active controls. Almost no trials (1%, 95% CI = 0.5 to 3) mention post-trial provisions. Most trials measure surrogate outcomes. Twenty percent (20%, 95% CI = 16 to 25) of trials measure patient-important outcomes, such as death; and the odds that these outcomes are in a low income country are five times greater than for a developed country (odds ratio (OR) 5.03, 95% CI = 2.70 to 9.35, p = < 0.001). Pharmaceutical companies are involved in 28% (CI = 23 to 33) of trials and measure surrogate outcomes more often than nonpharmaceutical companies (OR 2.45, 95% CI = 1.18 to 5.09, p = 0.31). CONCLUSION: We found a large discrepancy in the quality of reporting and approaches used in trials in developing settings compared to wealthier settings.

Full frame distilled prediction

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.
