Figure 2

Box plot of mean ADC values from each subject group for (a) the short-time scale (t = 1 ms) and (b) the long-time scale (t = 1.5 s). All mean ADC values of the healthy subjects are concentrated in a narrow range. The asthmatics have mildly elevated mean ADC values, and the subjects with COPD have markedly elevated mean ADC values. The three groups are better separated on the long-time-scale ADC (Short-time-scale: Pasthma-healthy = 0.038; PCOPD-healthy = 0.002; PCOPD-asthma = 0.005. Long-time-scale: Pasthma-healthy = 0.005; PCOPD-healthy < 0.001; PCOPD-asthma = 0.005.). Each box extends from the 25th percentile at lower edge to the 75th percentile at upper edge; the median is shown as a short line within the box. The upper and lower lines outside of the boxes represent the extreme values.
