Logistic regression analysis of pathological features of bone metastasis in colorectal cancer and related influencing factors after surgery

Table 4 Multiple logistic regression models analyzed the risk factors affecting postoperative bone metastasis in patients undergoing colorectal cancer surgery

Factor	Partial regression coefficient	SE	Wald	OR	95%CI	P value
The primary location of the tumor was a rectal cancer	1.128	0.322	17.527	2.456	1.644-3.674	< 0.001
With combined lymph node involvement	1.144	0.311	10.214	2.024	1.159-3.654	< 0.001
Combined lung metastases	1.134	0.241	14.327	3.124	2.124-5.544	< 0.001
No chemotherapy was administered after surgery	1.412	0.224	21.236	3.544	1.664-6.922	< 0.001

OR: Odds ratio; CI: Confidence interval.
