When the regression model was run with caffeine intake as a continuous variable, the model also predicted the paraxanthine/caffeine ratio (ANOVA: F 2,200 = 5.298, p = 0.006), with type-2 diabetes being a significant predictor (Beta = 0.145; p = 0.044) and caffeine intake exhibiting a strong trend to predict the ratio (Beta = 0.137; p = 0.056).
