Table 2.
Different models of logistic regressions to determine the cut-off point for the number and severity of the exacerbations that adds the greatest prognostic capacity to the FACED score in the construction cohort (n=819)
| Model 1 | Model 2 | Model 3 | |
|---|---|---|---|
| FACED | 2.13 (1.87–2.41) P<0.0001 |
2.14 (1.89–2.43) P<0.0001 |
2.15 (1.89–2.43) P<0.0001 |
| At least one hospitalization in the previous year, n=305 (37.2%) | 1.77 (1.22–2.61) P=0.03 |
||
| At least two hospitalizations in the previous year, n=127 (15.5%) | 1.56 (0.94–2.58) P=0.085 |
||
| Three or more hospitalizations in the previous year, n=68 (8.3%) | 1.33 (0.79–1.49) P=0.17 |
| Model 4 | Model 5 | Model 6 | Model 7 | |
|---|---|---|---|---|
| FACED | 2.45 (2.07–2.88) P<0.0001 |
