Pearson correlation and intraclass correlation coefficients for the measurements of FVC and FEV1 between the prototype and the plethysmograph, as well as their respective p-values. The 95% CIs for ICC are also presented. The two-way random effects model (2,1) was employed.
| Pearson Correlation | Intraclass Correlation | |||
|---|---|---|---|---|
| Metric | p-Value | ICC (2,1) (95% CI) | p-Value | |
| FVC | 0.992 | <0.001 | 0.987 (0.936 to 0.997) | <0.001 |
| FEV1 | 0.968 | <0.001 | 0.907 (0.609 to 0.981) | <0.001 |
