Figure 2From: Comparison of two different approaches in the detection of intermittent cardiorespiratory coordination during night sleepMethod 1 vs. Method 2: Correlation diagrams of subject b05. PCR1 vs. PCR2 and PR vs. PP of the data (black and gray lines) in Fig. 1. In this subject only the weighted phase coordination PCR is highly reproducible. In other subjects also the PR-PP correlation (see linear correlation coefficient r3 in Table 1) is striking.Back to article page
