Restoring patients to their baseline FEV1pp
Our fully-adjusted PS matching model (Model 2) suggests no difference in
final FEV1 improvement at discharge between the treated and untreated
groups. Steroid use was not associated with restoration of the CF
patient to their baseline FEV1pp (fully-adjusted β=-0.025, 95% CI:
-0.071, 0.020; Table 3). Patients who received steroid therapy restored
to an estimated 90.7% (standard error=2.1) of their baseline FEV1pp,
while patients who did not receive a steroid restored to an estimated
93.3% (SE=1.2) of their baseline FEV1pp; the difference in restoration
of baseline FEV1pp was 2.5% lower for encounters in which CF patients
were given a steroid (p-value=0.271). This was not statically
significant.
