Table 2.
Mean and standard deviation of repetition accuracy (percent correct syllable) across repetition conditions for the three PPA variant groups and the group of healthy controls (HC). Significant differences between conditions are indicated with superscripts as follows: frequent sentencesa, short meaningfulb, short non-meaningfulc, long meaningfuld, and long non-meaningfule phrases (p < 0.05; General linear model and Tukey’s test for the planned posthoc comparisons).
