Figure 2. Adjusted Cumulative Probabilities for Covariates in Final Multivariable Model for Prehospital Delays.
Odds ratios in the model represent cumulative probabilities between a predictor variable and each combination of higher risk versus lower risk outcome categories (e.g., >6 hours vs. ≤6 hours and >2 hours vs. ≤2 hours). Error bars denote 95% confidence intervals. Abbreviations: CABG, coronary artery bypass grafting; CAD, coronary artery disease; MI, myocardial infarction; PCI, percutaneous coronary interventions; SAQ, Seattle Angina Questionnaire. a Reference categories for the following variables: (1) Insurance status: Insured without financial concerns; (2) Marital status: Married; (3) Educational level: Graduate School; (4) Residential area: Urban; (5) Killip class: Killip class III or IV; (6) Time of hospital arrival: Weekend; (7) SAQ Angina frequency: No angina; (8) PHQ Depressive symptoms: Not depressed.
