We conducted an updated meta\u2010analysis of randomized controlled trials comparing bedtime versus morning antihypertensive administration, evaluating the overall treatment effect and its potential modification by baseline non\u2010dipper prevalence. PubMed, EMBASE, and the Cochrane Library were searched, with nighttime ambulatory systolic BP (SBP) and diastolic BP (DBP) as primary outcomes. Subgroup analyses were performed based on baseline non\u2010dipper proportion (&lt; 60%\u00a0vs. \u2265 60%).<\/jats:p>\n                  <jats:p>\n                    Sixty\u2010six RCTs involving 29,654 participants were included. In the overall hypertensive population, bedtime dosing significantly reduced nighttime SBP (WMD: 4.87\u00a0mmHg; 95% CI: 3.75\u20136.00) and DBP (WMD: 2.80\u00a0mmHg; 95% CI: 2.23\u20133.37), with modest reductions in 24\u00a0h SBP (WMD: 2.06\u00a0mmHg) and daytime SBP (WMD: 0.99\u00a0mmHg). In trials restricted to non\u2010dippers, a more pronounced reduction in nighttime BP was observed (SBP WMD: 7.57\u00a0mmHg; DBP WMD: 3.77\u00a0mmHg). Similarly, study populations with a higher baseline proportion of non\u2010dippers (\u2265 60%) experienced approximately two\u2010fold higher nighttime SBP reductions versus those with lower prevalence (&lt; 60%) (WMD: \u223c9.7\u00a0vs. 4.4\u00a0mmHg;\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.01), with a consistent pattern for nighttime DBP (5.1\u00a0vs. 2.6\u00a0mmHg; between\u2010group\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.05).\n                  <\/jats:p>\n                  <jats:p>Bedtime antihypertensive dosing reduces nocturnal BP across the general hypertensive population; however, the magnitude of effect appears to be modified at the study level by baseline non\u2010dipper prevalence.
