Figure 1 Percentage of time spent in the left lateral decubitus (LLD) and right lateral decubitus (RLD) positions among patients with congestive heart failure (CHF) and controls. Patients with CHF spent a significantly smaller percentage of sleep period time in the LLD position than the RLD position; 2.5% (0, 23.7) versus 22.8% (0, 52.7), respectively. No significant difference was observed among controls. Data are nonnormally distributed as indicated by box plots. Error bars = the 10th and 90th percentiles; horizontal lines = the median; rectangular boxes = 25th and 75th percentiles. *p < 0.05.
