  1. “No. of Cig.” and “Smoking years” mean the average number of cigarettes smoked per day and the length of habitual smoking in each subject. Other parameters are the same as in Table 1. Two subjects (S-1 and S-2) repeated the same measurement on different days, and the second data (-2) were shown below the first measurement (-1). The second data were excluded from the data calculation. G-Diff” indicates the statistical significance of the difference in the group mean values between smokers and non-smokers
