The visit-to-visit variability of both systolic blood pressure ( SBP ) and diastolic blood pressure ( DBP ) was independently associated with the occurrence of stroke -LSB- SD : the hazard ratios ( @ % confidence intervals ) of SBP and DBP were @ ( @ to @ ) and @ ( @ to @ ) ; CV : the hazard ratios ( @ % confidence intervals ) of SBP and DBP were @ ( @ to @ ) and @ ( @ to @ ) , respectively -RSB- .
