Poisson regression estimates of all predictor variables for the frequency of PExs 1-year post-baseline.

Parameter Rate ratio P 95% CI
CDAS 0.93 0.0006 (0.88, 0.96)
Frequency prior year PExs* 1.33 0.0014 (1.12, 1.58)
FEV1% predicted 0.99 0.37 (0.97, 1.0)
CRP 0.95 0.13 (0.89, 1.0)

Estimated via Poisson regression. CDAS: Clinical disease activity score, frequency of prior-year PExs, FEV1% predicted, and continuous CRP values were included as linear effects.
