Association Between FCI Score and SF-36 PFS at 1 Year (n = 47)*

	Bivariate	Multivariate**	R-squared for Multivariate
	Coefficient (95% CI)	Coefficient (95% CI)
Prospective (ICAP original)	−6.1 (−10.8 to −1.3)	−3.7 (−8.2 to 0.8)	0.17
Retrospective (Discharge summary)	−6.0 (−9.4 to −2.7)	−4.5 (−7.7 to −1.3)	0.20
Chart review (Gold standard)	−6.9 (−12.4 to −1.5)	−3.4 (−7.3 to 0.5)	0.18

Abbreviations: CI, confidence interval; RR, relative risk; SF-36 PFS, Short Form-36 Physical Function Subscale.

* Linear regression analysis with 47 patients that had complete chart review and completed SF-36 at 1 year. Reported coefficients represent the change in SF-36 PFS score at 1 year for every 1 unit increase in FCI score. A 1.5-unit difference in FCI score corresponds to a minimum important difference in SF-36 PFS score at 1 year.
