Distribution type was defined as follows: right-sided, involving the transverse or proximal colon; left-sided, involving the descending or distal colon; or bilateral, involving the entire colon. Low-dose aspirin included enteric-coated aspirin (100 mg) and buffered aspirin (81 mg). Non-aspirin antiplatelet agents included ticlopidine, clopidogrel, cilostazol, dipyridamole, sarpogrelate hydrochloride, ethyl icosapentate, dilazep, limaprost, and beraprost.
