The results showed that, following correction, the pooled MD for DBP remained highly significant at −7.83 mmHg (95% CI: −9.88 to −5.79, p < 0.0001).
The results showed that, following correction, the pooled MD for DBP remained highly significant at −7.83 mmHg (95% CI: −9.88 to −5.79, p < 0.0001).
In contrast, although the pooled point estimate for SBP in the stage 1 hypertension subgroup showed a downward trend (MD = −7.54 mmHg), it did not reach statistical significance (95% CI: −19.40 to 4.32; I 2 = 80.0%).DBP exhibited a different reduction pattern.
