NVAF, nonvalvular atrial fibrillation; MB, major bleeding; CRNM GIB, clinically relevant nonmajor gastrointestinal bleeding; OB positive, fecal occult blood positive; NAT, no antithrombotic treatment; AP, antiplatelet; VKA, vitamin K antagonists; NOACs, non-vitamin K antagonist; † compared with NAT, P-value <0.05; § compared with AP, P-value <0.05; △ compared with VKA, P-value <0.05.
