Clinical presentation predicts the outcome of patients with colon cancer

Table 4 Crude univariate analysis comparing the presentation of symptoms among survivors and non-survivors n (%)

Symptom	Survivors n = 142	Non-survivors n = 93	Univariate P value	Multivariate P value	OR (95%CI)
Pain	66 (46.2)	55 (59.1)	0.05	0.38	1.4 (0.7-2.8)
Diarrhea	13 (9.1)	13 (14)	0.24	0.51	1.5 (0.4-5.6)
Constipation	41 (28.7)	28 (30.1)	0.81	0.91	0.94 (0.3-2.7)
Vomiting	12 (8.4)	15 (16.1)	0.07	0.24	1.9 (0.6-5.6)
Weight loss	43 (30)	34 (36.6)	0.32	0.63	0.8 (0.4-1.7)
Rectal bleeding	34 (23.8)	13 (14)	0.06	0.004	0.25 (0.1-0.7)
Melena	2 (1.4)	5 (5.4)	0.1	0.04	7.4 (1.1-72.7)
Change in BH	56 (39.2)	42 (45.2)	0.36	0.96	1 (0.4-2.9)

A stepwise logistic regression model utilizing a likelihood ratio test was applied controlling for, age, stage and the duration of complaints. BH: Bowel habits.
