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

  Quartile 1 Quartile 2 Quartile 3 Quartile 4 p for trend
HR (95% CI)
Non-diabetes 1 (reference) 0.963 (0.34–2.75) 1.91 (0.79–4.6) 2.98 (1.28–6.95)* 0.014
Diabetes 1 (reference) 1.48 (0.89–2.46) 1.49 (0.90–2.47) 2.30 (1.45–3.67)* 0.004
LDL-C < 55 mg/dL 1 (reference) 0.41 (0.08–2.10) 1.49 (0.47–4.68) 3.94 (1.46–10.60)* 0.001
LDL-C ≥ 55 mg/dL 1 (reference) 1.15 (0.78–1.69) 1.33 (1.86–2.64)* 2.1 (1.56–3.09)* < 0.001
