Respiratory System Scale CFA loadingsa at baseline in sample of hospitalized patients: HARTI (N = 100). A Cough loaded on LRT and URT. B Cough loaded on LRT only. CFA confirmatory factor analysis, CFI comparative fit index, CI confidence interval, LRT lower respiratory tract, RMSEA root mean square error of approximation, RSV respiratory syncytial virus, TLI Tucker–Lewis index, URT upper respiratory tract, WRMR weighted root mean square residual. aFactor loadings and covariance are standardized and thus represent correlations. *P < 0.05. Sample: RSV-positive, observational study at baseline. Model fit statistics for cough on URT and LRT: CFI = 0.999; TLI = 0.997; RMSEA (95% CI) = 0.025 (0–0.127); chi-square test value (df = 7) = 7.429 (P = 0.3857); WRMR = 0.340. Model fit statistics for cough on LRT only: CFI = 1.000; TLI = 1.000 (estimate > 1.000 set to 1.000); RMSEA (95% CI) = 0.000 (0–0.115); chi-square test value (df = 8) = 7.728 (P = 0.4604); WRMR = 0.344
