Table 4: Test-retest change in measurements from Primary Study to Repeat Study in swallow function variables. Data are mean difference in the results of the six analysts with 95% confidence intervals of the difference shown in parentheses. Individual data for each study volunteer are shown (based on 1st analysis results only).
