Number of participants that the trial has enrolled 76835
Results
Propensity score matching (PS) and instrumental variable (IV) analyses were used to account for treatment selection. The incidence of post-treatment adverse events was lower in the TRI group by 0.95% compared to the TFI group with PS (p < 0.001) and by 0.34% with IV (p = 0.127). A significantly lower risk for access site bleeding was observed by 0.34% with PS (p < 0.001) and by 0.53% with IV (p < 0.001).

Baseline Characteristics
We retrospectively analyzed a large nation-wide registry in Japan to compare the incidence of post-treatment adverse events according to the types of vessel access (trans-radial; TRI vs. trans-femoral; TFI) among ACS cases (n = 76,835; 43,288 TRI group and 33,547 TFI group). 
Participant flow
Nation-wide registry data in Japan
Adverse events
No adverse events due to retrospective analyses
Outcome measures
Primary outcome was a composite of in-hospital death, myocardial infarction associated with percutaneous coronary intervention, bleeding complication requiring transfusion, and stent thrombosis during in-hospital stay.

Other
Other related information This is a retrospective study using J-PCI registry which is a national database of PCI in Japan. In Japan, there is no IIbIIIa inhibitors due to no govermental approval. In ACS, all are unfractioned heparin and DAPT with clopidogrel. Under the constant angicoagulation therapy, benefits of TRI is compared with transfemoral approach.
