Flow diagram documenting recruitment of subjects. A total of 619 subjects were admitted for sleep study, 466 of whom also completed ambulatory BP measurement. A total of 152 subjects were excluded from this current analysis because they were (A) AHI ≥ 5 and/or obese (B) inadequate ambulatory BP readings. The PLMS group had a significantly greater proportion of subjects who had been screened as potential high risk for OSAS (X2 = 4.89; P = 0.03)
