Abstract

fetched live from OpenAlex

In a scientifically ideal randomized controlled trial (RCT) on the efficacy of screening for lung cancer, screening-detected cases would be allocated to immediate intervention or to no action until symptoms lead to diagnostics. The study would provide for learning about the extent to which earlier interventions (defined by disease stage and stage-conditional tumor size) enhance curability, and also about the distributions of disease stage and stage-conditional tumor size at the time of diagnosis under the particular regimen of screening and its associated diagnostics. Because ethics call for randomization to screening or no screening, this contrast no longer provides for studying the curability function of shared concern for all regimens of screening; it addresses only the overall curability advantage specific to the regimen deployed. The same information that is provided by the scientifically ideal RCT is obtainable from a noncomparative study in which each member of the study cohort is subject to both screening and early intervention, so long as the problem of "overdiagnosis" is avoided by documenting growth before biopsy for cytologic or histologic criteria of malignancy and so long as the outcome of intervention is documented by follow-up. The ethically feasible RCT, in addition to compromising the objects of study, involves validity problems of its own and is less efficient by an order of magnitude.

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.

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.
