Association between Respiratory Intensity and Impact Questionnaire (RiiQ™) score and EQ‐5D‐5L index value score over time. EQ‐5D‐5L = EuroQol 5 Dimensions 5 Levels; RiiQ™ = Respiratory Intensity and Impact Questionnaire. Small random jitter is applied to the data points to allow for a clearer view on the data points. Spearman correlation coefficient (R) is presented. A linear regression line (with 95% confidence interval) is added to aid visualization. Co‐infections (N = 5) were excluded. EQ‐5D‐5L Index Value Scores <0 indicate a health state worse than death (likely due to underlying conditions)
