A comparison of the data for the number and shape of SMC nuclei between SVGD (+) and SVGD (−) subjects.

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: SMC = smooth muscle cell; SVGD = saphenous vein graft disease.
