Women have decreased pharyngeal critical pressure under hypotonic conditions (passive Pcrit) compared with men. A ∼2.0-cmH2O increase in passive Pcrit was observed in men compared with women (P < 0.02) in the entire group (left) and the male and female subgroups matched for respiratory disturbance index (RDI) and body mass index (BMI) (right). Values were adjusted for age and BMI. Line = median; box = 25th-50th percentiles; whiskers and cap = 95th percentile. Additional data points are represented that were outside the 5th and 95th percentiles. Bars = frequency histogram; dotted line = normal distribution plot; *P < 0.05.
