Table 2.  Baseline characteristics of patients attending the rehabilitation program according to subsequent survival and hospitalization

Table 3.  Predictors of all-cause mortality

Figure 1.  Survival curves (Kaplan-Meier) for the four quartiles of the i-BODE index. Quartile 1 is a score of 0 to 4, quartile 2 is a score of 5, quartile 3 is score of 6 and quartile 4 is a score of 7 to 10.

Figure 1.  Survival curves (Kaplan-Meier) for the four quartiles of the i-BODE index. Quartile 1 is a score of 0 to 4, quartile 2 is a score of 5, quartile 3 is score of 6 and quartile 4 is a score of 7 to 10.

Figure 2.  (a) Time to first admission for all causes (Kaplan-Meier). Log Rank = 32.5, p < 0.001. Quartile 1 is a score of 0 to 4, quartile 2 is a score of 5, quartile 3 is score of 6 and quartile 4 is a score of 7 to 10. (b) Time to first admission for COPD exacerbation (Kaplan-Meier). Log-Rank = 42.2; p < 0.001. Quartile 1 is a score of 0 to 4, quartile 2 is a score of 5, quartile 3 is score of 6 and quartile 4 is a score of 7 to 10.

Figure 2.  (a) Time to first admission for all causes (Kaplan-Meier). Log Rank = 32.5, p < 0.001. Quartile 1 is a score of 0 to 4, quartile 2 is a score of 5, quartile 3 is score of 6 and quartile 4 is a score of 7 to 10. (b) Time to first admission for COPD exacerbation (Kaplan-Meier). Log-Rank = 42.2; p < 0.001. Quartile 1 is a score of 0 to 4, quartile 2 is a score of 5, quartile 3 is score of 6 and quartile 4 is a score of 7 to 10.
