Randomized Controlled Trial
An experimental design in which study subjects are randomly assigned to an intervention group and a control group in order to evaluate the causal effect of the intervention. It is regarded as the gold standard of clinical research.

Randomized trials, controlled implementation studies, and interrupted time series are not new in academia, but in the actual evaluation of medical AI, their frequency of use is far lower than simple predictive performance reporting and before-and-after comparisons.
Randomized controlled trials, which eliminate selection bias by randomly assigning subjects to different intervention groups, are considered the gold standard in clinical research.
A randomized controlled trial (RCT) compared the effects of remote live-streaming versus pre-recorded video as two modalities for exercise training in chronic low back pain.
Correctly answering intervention-type questions requires additionally introducing domain knowledge, causal graphs, or carefully designed experiments (such as randomized controlled trials); data and computational power alone are insufficient.
Insulin shock therapy did not face a randomized controlled trial for the first time until the 1950s, failed the test, and immediately passed out of use.
Randomized controlled trials (RCTs) are regarded as the gold standard for causal inference in medicine and social science, but their external validity is often questioned.
Validation of medical therapies typically requires replication by independent teams, larger-sample randomized controlled trials (RCTs), long-term follow-up data, and peer-reviewed publication, with the entire cycle often spanning several years
