Abstract
Inflammatory bowel disease is a multifactorial disease. Oxidative stress has been thought to be one of etiologic factor for inflammatory bowel disease. The genes superoxide dismutase (SOD2) and NAD(P)H:quinone oxidoreductase 1 (NQO1) are involved in inflammation and oxidative stress. The purpose of the present case-control study with 134 patients with ulcerative colitis (UC) and 125 healthy controls was to determine whether polymorphisms of these genes, the NQO1 C609T and the SOD2 Ala-9Val, are associated with the risk of UC and influence the clinical characteristics. These polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphisms and direct sequencing. In patients showing steroid resistance, the number with the NQO1 T/T genotype was significantly higher than other genotypes (odds ratio 9.45, 95% confidence interval 2.46-41.6, p = 0.002). In the patients whose onset of UC was age 20 years or younger, more patients had SOD2 T/T genotype than the other genotypes (odds ratio 6.46, 95% confidence interval 0.82-51.0). No association between these polymorphisms and UC risk was apparent. The NQO1 C609T polymorphism may influence steroid resistance of UC patients, while the SOD2 Ala-9Val polymorphism may influence age of onset of UC. Oxidative stress may influence the clinical features of UC.

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
