From: Relationship between small dense low density lipoprotein and cardiovascular events in patients with acute coronary syndrome undergoing percutaneous coronary intervention

  Model 1* Model 2* Model 3*
Quartile 1 (reference)
Quartile 2 1.31 (0.91–1.89) 1.28 (0.88–1.87) 1.22 (0.87–1.79)
Quartile 3 1.77 (1.26–2.48) 1.65 (1.16–2.35) 1.39 (0.97–1.98)
Quartile 4 2.33 (1.68–3.23) 2.21 (1.57–3.09) 1.71 (1.21–2.41)

  1. Values are hazard ratio (95% confidence interval) unless otherwise indicated. Quartile 1: < 18.5 mg/dL, Quartile 2:18.5–25.5 mg/dL, Quartile 3: 25.5–35.1 mg/dL, Quartile 4: ≥ 35.1 mg/dL. * Model 1: age, gender, BMI; Model 2: model 1 + smoking status, hypertension, previous MI, previous stroke, syntax score, number of stents, total length of stents. Model 3: model 2 + TG, LDL-C, HDL-C, HbA1C, high sensitivity C-reactive protein, lipid-lowering medication use. Hazard ratios and 95% confidence intervals were obtained from Cox proportional hazards models
