Table 1. Does the blood pressure entry criterion have an effect on the baseline blood pressure variability?
Baseline values (Review 1 and 2) | Entry based on DBP criterion | Entry based on SBP criterion | Entry based on either SBP or DBP criterion |
Mean SD of SBP±SE mmHg | 14.0±0.6 (n = 41) | 9.3±1.1* (n = 5) | 9.7±1.6* (n = 10) |
Mean SD of DBP±SE mmHg | 5.3±0.3† (n = 44) | 8.4±0.7 (n = 4) | 4.6±0.6† (n = 10) |
SD = Standard Deviation; SE = Standard Error; SBP = Systolic Blood Pressure; DBP = Diastolic Blood Pressure; n = number of observations.
p<0.01 unpaired t test of mean SD of SBP as compared to entry based on DBP criterion.
p<0.01 unpaired t test of mean SD of DBP as compared to entry based on SBP criterion.
