ADP = adenosine diphosphate. DOAC = direct-acting oral anticoagulant. LMWH = low-molecular-weight heparin. NSAID = non-steroidal anti-inflammatory drug. OR = odds ratio. PPI = proton pump inhibitor. SNRI = serotonin and norepinephrine reuptake inhibitor. SSRI = selective serotonin reuptake inhibitor.
