- Yes
- Confounders controlled for Confounding factors that have been accounted for by stratification or model adjustment
- age, sex, Confounders controlled for: "autoantibody presence" is not in the list (abnormal glucose tolerance, acetaldehyde, acute graft vs. host disease, acute lymphoblastic leukemia, acute myeloid leukemia, adenoma, age, AIDS, alcohol consumption measurement, alcohol drinking, ...) of allowed values.autoantibody presence, Confounders controlled for: "Human leukocyte antigens (HLA) genotype" is not in the list (abnormal glucose tolerance, acetaldehyde, acute graft vs. host disease, acute lymphoblastic leukemia, acute myeloid leukemia, adenoma, age, AIDS, alcohol consumption measurement, alcohol drinking, ...) of allowed values.Human leukocyte antigens (HLA) genotype
