Table 3: Intra and inter-rater reliabilities of Task 1, 2, 3, and total FIT-HaNSA scores for the WAD2 (n=18) and control (n=41) participants. Different numbers of participants (indicated below) were included in the Intra and inter-rater reliability calculations. Intraclass correlation coefficients (ICC2,1) with 95% confidence intervals (in parentheses) are presented.
