  Figure 2. Adjusted* time-varying mortality rates by receipt of optimal care and clinical risk obtained from a flexible parametric model (odds scale, five degrees of freedom) with time varying covariates by GRACE risk score category for optimal care vs. suboptimal care across the full care pathway (A) and by the following subgroups of the care pathway: pharmacological therapies (B)†, investigative and invasive coronary strategies (C)‡, and lifestyle (D)§,^. P = 0.004 for interaction. GRACE, Global registry of Acute Coronary Events, categorized into low (<109), intermediate (109 to ≤140), and high (>140) risk. *Model adjusted for demographic characteristics including sex, year, deprivation, previous acute myocardial infarction, previous angina, previous PCI, previous CABG, hypertension, peripheral vascular disease, chronic renal failure, chronic heart failure, cerebrovascular disease, diabetes mellitus, smoking status, and elevated cholesterol. †Including pre-hospital receipt of aspirin, aldosterone antagonist during admission, aspirin on discharge, P2Y12 inhibition on discharge, ACE inhibitors (ACEi)/angiotensin receptor blockers (ARBs) on discharge, β-blocker on discharge, and HMG Co-A…

  Figure 3. Unadjusted landmark Kaplan–Meier survival curves and crude mortality rates by GRACE risk score category and receipt of optimal care vs. suboptimal care. This figure demonstrates the benchmarked crude mortality rates for the following time periods; 0–1 year, 1–2 years, 2–3 years, 3–8 years, across GRACE risk category by the receipt of optimal care. The percentages represent the crude mortality rates for each time period with the 95% confidence interval for each of the respective GRACE risk score categories. Population at risk at baseline; low GRACE risk category: 73 351, intermediate GRACE risk category: 59 201, high GRACE risk category: 52 005. Population at risk 3–8 years; low GRACE risk category: 70 069 intermediate GRACE risk category: 47 120, high GRACE risk category: 28 698.
