Figure 1 Study Population and Outline of the Study
Flow chart of the study population showing the number of subjects, divided in subgroups by genetic status, considered in the different analyses performed on and off beta-adrenergic blockers (BBs). For the study on BB, the number of subjects was limited to those with both measurements—on- and off-treatment—available, allowing for paired comparisons. BRS = baroreflex sensitivity; HR = heart rate; MC = mutation carriers; N.M.C. = nonmutation carriers; SA = South African; WO = Wash-Out.
