Over a median follow-up of 9.8 years , the intensive-therapy group had a significantly lower risk of the primary outcome than did the standard-therapy group ( hazard ratio , 0.83 ; 95 % confidence interval [ CI ] , 0.70 to 0.99 ; P = 0.04 ) , with an absolute reduction in risk of 8.6 major cardiovascular events per 1000 person-years , but did not have reduced cardiovascular mortality ( hazard ratio , 0.88 ; 95 % CI , 0.64 to 1.20 ; P = 0.42 ) .
