Although the crude OR was not statistically significant (OR 0.47; 95% CI: 0.21–1.09; p = 0.08), the association became highly significant after adjustment in Model 1 (adjusted OR 0.18; 95% CI: 0.06–0.58; p = 0.004) and Model 4 (adjusted OR 0.23; 95% CI: 0.08–0.65; p = 0.006), suggesting a lower likelihood of OMT among older patients.
Elective PCI: Presentation with acute coronary syndrome (ACS) showed a trend toward higher OMT prescription (crude OR 3.06; 95% CI: 0.81–11.52; p = 0.10), but this did not reach significance in adjusted models (Model 1 adjusted OR 2.79; 95% CI: 0.57–13.51; p = 0.206), suggesting the association may be influenced by confounding. eGFR <60 ml/min/1.73 m 2 : In the unadjusted analysis, reduced eGFR was associated with a non-significant increase in odds of receiving OMT (OR 3.49; 95% CI: 0.61–20.01; p = 0.16).
