Table 1. Patient Demographics for FTLD-tau and FTLD-TDP groups.

Descriptive statistics across patient groups for baseline variables. Median and interquartile range (median[IQR]) are provided. Mann-Whitney-Wilcox was performed for continuous variables and chi-squared test was performed for categorical variables; p value is based on comparison between groups.
