text: Table 2 shows mean responses to the 15 dyspnea 
  questions for each disease classiﬁcation and presents 
  question weights (PCA scoring coefﬁcients) used for 
  calculating the dyspnea impact assessment. 
  
  Individuals with PRISm reported the highest dyspnea 
  impact, with a signiﬁcantly greater mean score (63.0; 
  95% CI, 59.5-66.4) than those with undiagnosed 
  asthma or COPD (Table 3). Those with undiagnosed 
  asthma or COPD had similar mean scores (56.6; 
  95% CI, 53.9-59.3 and 57.5; 95% CI, 55.1-59.9, 
  respectively), followed by those with normal 
  spirometry (51.8; 95% CI, 50.7-52.8). All four groups 
  reported signiﬁcantly more impactful dyspnea than 
  the control group (mean score, 13.8; 95% CI, 11.8- 
  15.7). Table 3 shows between-group differences in 
  mean dyspnea impact assessments for each pair of 
  disease outcomes. Figure 2 compares box plots of the 
  dyspnea impact assessment values across disease 
  classiﬁcations.
