The adjusted cubic spline model on the association between L/A ratio on a continuous scale and adjusted risk of 28-day all-cause mortality in patients with AMI. Crude hazard ratio (HR) and 95% CI for L/A ratio in 28-day mortality(A). Adjusted HR and 95% CI for L/A ratio in 28-day mortality (B). Adjusted variables included age, gender, SBP, DBP, hypertension, diabetes, hyperlipemia, AF, COPD, CHF, aspirin, clopidogrel, beta blockers, diuretics, digitalis, statin, insulin, oral hypoglycemic agents, BUN, Scr, glucose, WBC, Hb, BE, SpO₂.
