Thickness and area of the whole venous wall and its layers in all patients enrolled in the study and in patients with and without a diagnosis of SVGD (SVGD (+) vs. SVGD (−)).

aVariables are expressed as the mean ± standard deviation with the 25th and the 75th percentiles in brackets.bVariables are expressed as the mean ± standard deviation and as numbers (n) with percentages (%) for the values below the 25th percentile (L) and exceeding the 75th percentile (H).NOTICE: The sum of the SVGD (+) and SVGD (−) patients is lower than the total number of patients enrolled in the study because some study participants did not undergo late coronary evaluation (see the text).Abbreviations: %MedAr = relative tunica media area (MedAr/WallAr); %MedTh = relative tunica media thickness; AdvAr = adventitia area; AdvTh = adventitia thickness; IntAr = tunica intima area; IntTh = tunica intima thickness; MedAr = tunica media area; MedTh = tunica media thickness; SVGD = saphenous vein graft disease; WallAr = entire area of SV wall; WallTh = thickness of the SV wall.
