Below age 50 , DBP24 was the main driver of risk , reaching significance for total ( HR for 1-SD increase , 2.05 ; P = 0.0039 ) and cardiovascular mortality ( HR , 4.07 ; P = 0.0032 ) and for all cardiovascular end points combined ( HR , 1.74 ; P = 0.039 ) with a nonsignificant contribution of SBP24 ( HR0 .92 ; P0 .068 ) ; above age 50 , SBP24 predicted all end points ( HR1 .19 ; P0 .0002 ) with a nonsignificant contribution of DBP24 ( 0.96 HR1 .14 ; P0 .10 ) .
