FIGURE 4.

Patient-Reported Outcomes (PROs). PROs for dyspnea, physical function, fatigue, and lower back pain. Higher dyspnea scores (range 0–99) indicate increased severity of dyspnea with common daily activities. Higher physical function scores (range 20–99) indicate increased physical function and ability to carry out daily life activities. Higher fatigue scores (range 8–40) indicate increased fatigue on average over the past week. Higher lower back pain scores (range 0–50) indicate greater severity of lower back pain and impact on life.
