Association of plasma concentrations of Cer (d18:1/16:0) with MACE in the full cohort and in patients with ACS or SAP. The results are presented as hazard ratios (HRs) for Cer(d18:1/16:0) above versus below the median, with 95% CIs. ACS, acute coronary syndrome; Cer, ceramide; MACE, major adverse cardiac event; SAP, stable angina pectoris.
