Abstract
The genes that contribute to the genetic susceptibility to chronic obstructive pulmonary disease (COPD) remain largely unknown. We hypothesized that widely divergent rates of decline in lung function in smokers would be a robust phenotype for detection of genes that contribute to COPD severity. We selected 283 rapid decliners (deltaFEV1 = -154 +/- 3 ml/yr) and 308 nondecliners (deltaFEV1 = +15 +/- 2 ml/yr) from among smokers followed for 5 yr in the NHLBI Lung Health Study. Rapid decline of FEV1 was associated with the MZ genotype of the alpha1-antitrypsin gene (odds ratio [OR] = 2.8, p = 0.03). This association was stronger for a combination of a family history of COPD with MZ (OR = 9.7, p = 0.03). These data suggest that the MZ genotype results in an increased rate of decline in lung function and interacts with other familial factors. Haplotype frequencies of the microsomal epoxide hydrolase (mEH) gene were significantly different between rapid decliners and nondecliners (p = 0.03). A combination of a family history of COPD with homozygosity for the His113/His139 mEH haplotype was also associated with rapid decline of lung function (OR = 4.9, p = 0.04). The alpha1-antitrypsin S and 3' polymorphisms, vitamin D-binding protein isoforms, and tumor necrosis factor (TNF-alpha G-308A and TNF-beta A252G) polymorphisms were not associated with rate of decline of lung function.

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
