Key result
Diastolic phase 4 and phase 5 blood pressure measurements were highly correlated (r = 0.98) with a median difference of 1 mmHg, though differences ≥5 mmHg occurred in 9% of subjects.

High correlation supports similar clinical interpretation of phase 4/5 diastolic BP; leaves open whether phase choice affects risk stratification in subgroups.
Cross-Sectional (n=18,325)
Effect estimate: r = 0.98
Diastolic phase 4 and phase 5 blood pressure measurements are highly correlated with a median difference of only 1 mmHg, though larger differences can occur depending on BP level and BMI.
Lichtenstein et al. (1986) reported a cross-sectional. Diastolic phase 4 (D4) blood pressure measurement vs. Diastolic phase 5 (D5) blood pressure measurement was evaluated on Relationship and difference between diastolic phase 4 and phase 5 (r = 0.98). Diastolic phase 4 and phase 5 blood pressure measurements were highly correlated (r = 0.98) with a median difference of 1 mmHg, though differences ≥5 mmHg occurred in 9% of subjects.
