Step 3: Weighted model scores

Model	Mean ± SD	Score range	OR (95% CI) per point increase in score	AUC (95% CI)
LT-FS-Base	19.2 ± 8.2	10 – 36.0	1.11 (1.06, 1.16)	0.73 (0.66, 0.81)
LT-FS-Body Composition	20.5 ± 8.9	10 – 42.4	1.11 (1.06, 1.15)	0.74 (0.66, 0.82)
LT-FS-Biomarker	24.6 ± 10.7	10 – 60.3	1.11 (1.07, 1.15)	0.78 (0.69, 0.86)
Model	Mean ± SD	Score range	OR (95% CI) per point increase in score	AUC (95% CI)
SPPB	9.3 ± 3.1	0 – 12	1.08 (0.98, 1.19)	0.58 (0.48, 0.67)
FFP	1.9 ± 1.2	0 – 5	1.12 (0.82, 1.53)	0.55 (0.44, 0.66)

Each variable in Step 2 models were multiplied by their parameter estimates estimated by logistic regression and combined to create an index score range. This table demonstrates the performance characteristic of each model score (e.g., mean scores, ranges, score associations with death and delisting by linear regression, and model area under the curves (AUC) for waitlist death and delisting. The same characteristics of the existing SPPB and FFP measures are presented for comparison. See http://lungtransplantfrailtyscale.ucsf.edu for an online calculator
