At late angiography ( median 247 days ; 90 % of eligible patients ) , patients in the EES arm had a significantly larger minimal lumen diameter ( 2.03 0.7 mm vs. 1.80 0.6 mm ; p < 0.01 ) ( absolute mean difference : 0.23 mm ; 95 % CI : 00.7 to 0.38 ) , net lumen gain ( 1.28 0.7 mm vs. 1.01 0.7 mm ; p < 0.01 ) , and lower percent diameter stenosis ( 23 22 % vs. 30 22 % ; p < 0.01 ) and binary restenosis rate ( 11 % vs. 19 % ; p = 0.06 ) , compared with patients in the DEB arm .
