Exposure	Non-adjusted		Adjust I		Adjust II
Catheter placement method	OR (95 %CI)	P-value	OR (95 %CI)	P-value	OR (95 %CI)	P-value
Open surgery	1.0		1.0		1.0
Seldinger technique	1.715 (0.669, 4.396)	0.262	1.456 (0.543, 3.906)	0.456	1.061 (0.308, 3.649)	0.926
Modified Seldinger technique	0.276 (0.061, 1.257)	0.096	0.247 (0.051, 1.198)	0.083	0.161 (0.027, 0.961)	0.045

Data in the table: OR (95 % CI) P-value;

Non-adjusted model adjusts for: gender, age;

Adjust I model adjust for: gender, age, systolic pressure, history of abdominal and pelvic surgery, creatinine;

Adjust II model adjust for: gender, age, BMI, systolic blood pressure, diastolic blood pressure, diabetes, hypertension, history of glomerulonephritis, history of ischemic heart disease, history of abdominal and pelvic surgery, hemoglobin, urea nitrogen, creatinine, duration of catheter placement procedure (min)
