DBP approached significance (P = 0.06), likely limited by small sample sizes and measurement heterogeneity (ambulatory vs. office BP) ( De Bhailis and Kalra, 2022 ; Chen et al., 2021 ).
DBP approached significance (P = 0.06), likely limited by small sample sizes and measurement heterogeneity (ambulatory vs. office BP) ( De Bhailis and Kalra, 2022 ; Chen et al., 2021 ).
However, DBP showed a trend toward association with postoperative hypertension (DBP: OR = 1.17, 95% CI: 0.99–1.38, P = 0.06, I 2 = 30%), approaching but not meeting our predefined significance threshold (P < 0.05).
This near-significant result may reflect limited statistical power due to heterogeneous DBP measurement protocols across studies or a true but modest effect requiring larger samples to confirm.
