Table 1 Distribution of patient demographic and clinical variables by site

Demographic/Clinical^a	Inpatients (n = 42)	Outpatients (n = 42)	Site Difference (χ², p)^b
Age in years (Mean; Range)	57 (40-78)*	66 (47-94)	4.0, < 0.01^c
Sex (M:F)	23:19*	42:0	24.6, < 0.01
Cancer Stage (IIIA&B: IV)	10:32	9:33	2.1, 0.36
Prior Therapy (Yes:No)	21:20 ^d*	10:32	6.7, 0.01
WHO ECOG (0:1:2)	17:18:07	13:24:04^d	2.2, 0.33
COPD (No:Mild:Mod:Severe)^c		14:7:13:8

^aValues are numbers of patients except for Age. ^bBased on chi-square test. ^cBased on t-test. ^dOne patient at MRMC lacked documentation of prior therapy, while another patient at VAMC lacked documentation on ECOG scale. *Significant difference at p < 0.05 compared to outpatients.
