Outcomes of COPD Exacerbations Treated with Corticosteroids, Antibiotics, or Both

Figure 2

Graph of symptom index for representative exacerbation (Patient #8). The dashed horizontal line represents the preexacerbation Symptom Index baseline (as determined from the graph); the solid vertical line marks the day when treatment was initiated. In this example, the Symptom Index returns below the preexacerbation baseline on Day #2 following the initiation of treatment and remains there until Day #21, indicating a treatment success. (Note that some data points are missing due to patient not reporting on those days.)
