Fig 1 Propensity scores for dual-antiplatelet therapy (DAPT) use (red bars) compared with aspirin (acetylsalicylic acid [ASA]) monotherapy (blue bars). The propensity score for DAPT use is the probability, given baseline covariates, that any patient in either group is prescribed DAPT.

Fig 2 Major adverse cardiovascular events (MACEs) and limb outcomes among patients prescribed dual-antiplatelet therapy (DAPT; red line) vs aspirin (acetylsalicylic acid [ASA]; blue line) monotherapy. Patients prescribed DAPT had significantly lower rates of (A) MACEs, (B) overall mortality, and (C) major amputation or death. D, There was no significant association between DAPT and major adverse limb events (MALEs).

Fig 3 Aspirin (acetylsalicylic acid [ASA]) and clopidogrel resistance among patients treated with dual-antiplatelet therapy (DAPT). There was no significant association between (A) clopidogrel resistance (P2Y12 reaction units [PRU], <235 [blue line] vs ≥235 [red line]) or (B) aspirin (ASA) resistance (aspirin reaction units [ARU], <550 [blue line] vs ≥550 [red line]) and the combined end point of death, myocardial infarction (MI), stroke, or target vessel revascularization.
