Figure 1: (A) Correlation between PaCO_{2} and PtcCO_{2} shows a coefficient r=0.73. Regression analysis: PaCO_{2}=0.63Ã—PtcCO_{2}+ 12.89, r=0.73, p<0.01. (B) Bias and LOA between PaCO_{2} and simultaneously measured PtcCO_{2} measurements. The solid line represents the mean of the differences (= bias) between PaCO_{2} and PtcCO_{2} (3.8±1.85 mmHg). The dashed lines are equivalent to 2SDs of the means (= LOA). |
