Table 1 GRADE for the certainty of evidence
From: Dual antiplatelet management in the perioperative period: updated and expanded systematic review
Outcome | Study limitations | Consistency | Directness | Precision | Certainty of evidence |
|---|---|---|---|---|---|
Holding DAPT for more than 2 days vs less than ≤ 2 days | |||||
 CABG surgery | |||||
  Bleeding is less | Serious limitations | Inconsistent | Direct | Imprecise | Low |
  Transfusion is less | Serious limitations | Inconsistent | Direct | Imprecise | Low |
  Re-exploration is less | Serious limitations | Inconsistent | Direct | Imprecise | Low |
