Abstract
Recent reports have highlighted the distinct roles and occasional tension between randomised controlled trials (RCTs) and population-based observational research ( Concato, 2012 ; Hershman and Wright, 2012 ; Goodwin et al, 2013 ). In this commentary, we will discuss the relative strengths and limitations of each form of research (see Table 1 ), and propose that well-designed RCTs and population-based observational studies can serve as complementary forms of research to ensure that the results of clinical trials translate into tangible benefits in the general population.

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
