Table 1 Characteristics of the Study Population (n = 137), Grouped by GOLD 2011 Stage at Baseline*
Figure 1 One-year probabilities of transition between different GOLD 2011 (A) and GOLD 2017 (B) stages during a 2-year follow-up. Circles represent a single state for the beginning of each 1-year period. Straight arrows represent the probability of changing to another stage; curved arrows represent continuing in the same stage for another 1-year period.
