The Reliability of Pharyngeal High Resolution Manometry with Impedance for Derivation of Measures of Swallowing Function in Healthy Volunteers

Figure 3

Intraclass correlations between the mean SRI using 1 to 10 consecutive swallows versus the all-swallow mean SRI. Data are based on 1st analysis results for Primary and Repeat Studies combined (10 measures, two per analyst). Analyst minimum and maximum ICC are grey dotted lines. Note: excellent reliability (ICC > 0.8) was found for all analyst results (i.e., when the grey dotted line representing minimum analyst ICC breaches the 0.8 threshold) when the SRI was based on the average of at least four consecutive swallows (arrow).
