p refers to the significance of interaction effect of plasma biomarkers concentration × time. The p-values are adjusted using false discovery rate (FDR). Beta (SE) refers to standardized regression coefficient with standard error. Cohen’s d refers to effect size of interaction effect of plasma biomarkers concentration × time. Positive effect size d means higher plasma p-tau are correlated with faster ADAS13 score increase. Negative effect size d means higher baseline plasma p-tau concentration is correlated with faster MMSE score decrease.
