Table 4 Risk of cardiovascular events across concordance/discordance groups stratified by diabetes status

From: Discordance between the triglyceride glucose index and fasting plasma glucose or HbA1C in patients with acute coronary syndrome undergoing percutaneous coronary intervention predicts cardiovascular events: a cohort study from China

  1. FPG fasting plasma glucose, HbA1C Glycosylated haemoglobin, TyG triglyceride glucose, HR hazard ratio, CI confidence interval
  2. Different cutoff values were used by diabetes status. In non-DM group: Median HbA1C: 5.8%, median FBG: 5.52 mmol/L, median TyG: 8.74; In DM Group: guideling-guide HbA1C: 7.0%, equivalent percentage FPG: 7.11 mmol/L, equivalent percentage TyG:8.95
  3. aThe log-rank test and backward stepwise selection methods in a Cox proportional hazards regression model was performed; adjusted for age, sex, BMI, current smoker, hypertension, previous MI, previous stroke, previous PCI, previous CABG, non-HDL-C, lipid-lowering and antidiabetes medication use
