Box and whisker plots of the distribution of DSS between (a) non-current smokers (n = 43) and current smokers (n = 18) and between (b) non-smokers (n = 27) and smokers (n = 34). The box represents the interquartile range that contains 50% of the values, and the whiskers extending from the box represent the highest and lowest values. The thick line in the box represents the median value. There was a significant difference in DSS between non-current smokers and current smokers (A, P = 0.011), whereas no difference was found between non-smokers and smokers (B, P = 0.328)
