Model and AUC for the receiver operating characteristic for the 3 models that were tested to predict 6MWT distance threshold

Variable	Model 1 β-coefficient	95% CI	p value	AUC (95% CI)	Model 2 β-coefficient	95% CI	p value	AUC (95% CI)	Model 3 β-coefficient	95% CI	p value	AUC (95% CI)
Median gait cadence (steps/min)	0.198	0.028, 0.369	0.023	0.734 (0.571,0.900)	0.323	0.066, 0.579	0.014	0.810 (0.669,0.950)	−	−	−	0.640 (0.457, 0.822)
Height (m)	−	−	−	−	11.67	1.06, 22.28	0.031	−	−	−	−
DASI score	−	−	−	−	−	−	−	−	0.049	−0.001, 0.107	0.103

There was no difference between the AUCs of all the models in the ability to predict patients that would walk >370 m during 6MWT (p = 0.215). CI, confidence interval; 6MWT, 6-min walk test; DASI, Duke Activity Status Index; AUC, area under the curve.
