Calculated as the average value of each parameter on two consecutive days in all 116 patients: 39 nonmedicated patients with hypertension and 77 medicated patients with hypertension and obstructive sleep apnea. Data are expressed as mean ± standard deviation (SD). The individual values of each parameter were calculated as the average of two consecutive nights.
*P < .01 and **P < .05 vs nonmedicated patients with hypertension by t test; ***P < .05 vs all patients by t test.
