From: Transient intracranial pressure elevations (B waves) are associated with sleep apnea
Visualization of ICP changes during all apnea events across all patients. A The average ICP change during apnea events is plotted over time. The shaded region indicates the SEM at each time point for the compiled dataset comprising all apnea events across the patients. B Boxplots demonstrating the distribution of ICP changes across the sleep stages (N1, N2, N3, REM) and the total, along with individual data points. Each box indicates the interquartile range (IQR), with the median ICP change highlighted by a red line. The whiskers extend from the box to data points within 1.5 times the IQR. Median ICP change for N1: 6.4 mmHg, N2: 8.4 mmHg, N3: 8.6 mmHg, REM: 13.2 mmHg, and total: 8.1 mmHg
