Association between IDO2 percent methylation at position cg11251498 with age or normalized MMSE (normMMSE) for baseline diagnosis and in view of conversion within 76 months. Model 1 adjusted for age, gender, education and diagnosis/converters, while model 2 adjusted for model 1 + lifestyle factors (tobacco use, alcohol use, and body mass index (BMI))

Abbreviations: normMMSE normalized mini mental state exam, β beta value, S.E. standard error, t t statistic, 95% CI 95% confidence interval
