End-of-intervention efficacy outcomes and change of outcome from baseline visit by group: patients

End of Intervention	Arm 1 (n = 34) [Median (IQR) or n (%)]	Arm 2 (n = 18) [Median (IQR) or n (%)]	Mean Difference (95% CI; P Value)*
Knowledge	13 (12–13)	12 (12–13)	0.86 (−0.09 to 1.81; 0.075)
Preparedness	8 (7–9)	7 (7–8)	−0.42 (−1.85 to 1.02; 0.57)
Confidence	9 (7–10)	8 (7–10)	0.13 (−1.36 to 1.61; 0.86)
Advance care planning	21 (62)	6 (33)	3.28 (0.95 to 11.26; 0.059)†

Definition of abbreviations: CI = confidence interval; IQR = interquartile range.

A positive mean shows that the intervention increases the score more than the control.

^*Effect of arm 1 on mean difference of score change from baseline adjusted for age, sex, and baseline FVC.

^† Odds ratio (P value) adjusted for age, sex, and baseline FVC.
