Co-morbidity, not age predicts adverse outcome in Clostridium difficile colitis

Table 1 Patient age and sex vs outcome at discharge (n, %, mean ± SD)

Variable	Alive	Dead	P value
Patient age (yrs)	76.1 ± 15.0	78.9 ± 13.5	0.383 (1, a)
Patient sex (M/F)	36/58	10/17	0.546 (2)
Age 1 (yrs)
23-79	45 (83%)	9 (17%)
80-97	48 (73%)	18 (27%)	0.192 (2)
Age 2 (yrs)
23-59	12 (92%)	1 (8%)
60-69	12 (75%)	4 (25%)
70-79	21 (84%)	4 (16%)
80-97	49 (73%)	18 (27%)	0.428 (2)
Age 3 (yrs)
23-59	12 (92%)	1 (8%)
60-69	12 (75%)	4 (25%)
70-79	21 (84%)	4 (16%)
80-89	37 (71%)	15 (29%)
90-97	12 (80%)	3 (20%)	0.577 (2)

(1):Student t test; (2):Fisher’s exact test; (a):Additional logistic regression analysis. Age (as continuous variable) did not predict adverse outcome or death (P = 0.382).
