Adjusted mortality for comparison of ‘Good’ care in women with ‘Fair’ care in women with 95% CIs: 2.7% (2.5–3.0%), P < 0.001. Adjusted mortality for comparison of ‘Excellent’ care in women with ‘Good’ care in women with 95% CIs: 1.4% (1.2–1.6%), P < 0.001. OBQI score is ordered into four categories: ‘Excellent’, ‘Good’, ‘Fair’, and ‘Poor’. ‘Excellent’ refers to an OBQI score of 100, ‘Good’ refers to a score of ≤100 and ≥83, ‘Fair’ refers to a score of ≥67 and <83, and ‘Poor’ refers to a score of <67. Mortality rates are adjusted for age, ethnicity, family history of coronary heart diseases, ischaemic ECG changes, history of heart failure, left ventricle systolic dysfunction, hypercholesterolaemia, history of myocardial infarction, history of cerebrovascular accident, history of peripheral vascular disease, hypertension, smoking, asthma/chronic obstructive pulmonary disease, and admission under a consultant cardiologist. Lives saved are estimated for regions where women’s care by mean OBQI was in a lower category than that for men, where the number of women included in the study period is multiplied by the difference in mortality rates.
