Outcome of patients with primary sclerosing cholangitis and ulcerative colitis undergoing colectomy

Table 4 Multivariate analysis models showing the association between primary sclerosing cholangitis patients with ulcerative colitis who underwent colectomy and the primary endpoints

Multivariate analysis	P value	OR	95%CI
Model 11
Platelet (× 109/L)	0.030	0.991	0.98-0.999
Albumin (g/dL)	0.006	0.05	0.007-0.44
Model 22
Pre-operative Mayo risk score	0.390	1.2	0.77-1.97
Hemoglobin (g/dL)	0.010	0.6	0.45-0.91
Model 33
Pre-operative MELD score	0.090	18.6	0.6-567
Hemoglobin (g/dL)	0.090	0.03	0.001-1.9

¹Model 1, to avoid overestimation of the model, we excluded the Mayo risk score and the Model for End-Stage Liver Disease (MELD) score from model 1;

²Model 2, we included the Mayo risk score in the model and removed the individual variables used for Mayo risk score calculation;

³Model 3, we included the MELD score in the model and removed the individual variables used for MELD score calculation. P < 0.05, all variables with P < 0.1 in a univariate analysis were included in the multivariate analysis models.
