From: Kinesthetic stimulation for obstructive sleep apnea syndrome: An “on-off” proof of concept trial
Boxplots representing the duration of respiratory events during Stim on and Stim off periods for each of the 24 patients: (A) Apnea duration and (B) Hypopnea duration. The box spans the interquartile ranges and the median is indicated by a circle. Statistical difference annotated by *p < 0.05 using a Wilcoxon signed rank test. Patient 24 did not show any apnea event during the Stim on periods.
