Analysis of risk factors for polypoid lesions of gallbladder among health examinees

Table 1 Instructions of assignment of variables for polypoid lesions of gallbladder

	Female = 0	Male = 1
BMI	(< 28) = 0	(≥ 28) = 1
T-Cho	Normal or decreased = 0	Increased = 1
TG	Normal or decreased = 0	Increased = 1
HDL-C	Normal or increased = 0	Decreased = 1
LDL-C	Normal or decreased = 0	Increased = 1
Blood glucose	Normal or decreased = 0	Increased = 1
HBsAg	(-) = 0	(+) = 1
Gallstones	(-) = 0	(+) = 1
Fatty liver	(-) = 0	(+) = 1

BMI: Body mass index; T-Cho: Cholesterol; TG: Triglyceride; HDL-C: High density lipoprotein; LDL-C; Low density lipoprotein; HBsAg: Hepatitis B surface antigen.

^aP < 0.05 vs negative PLG. PLG: Polypoid lesions of gallbladder; BMI: Body mass index; T-Cho: Cholesterol; TG: Triglyceride; HBsAg: Hepatitis B surface antigen; HDL-C: High density lipoprotein; LDL-C; Low density lipoprotein.

Table 3 Logistic regression analysis of multiple relevant factors of polypoid lesions of gallbladder

Variables	OR	95% CI	P value
Sex	1.843	1.245-2.789	0.0035
HBsAg	2.563	1.875-3.418	< 0.001
HDL-C	3.346	2.932-4.133	< 0.001

OR: Odds ratio; HBsAg: Hepatitis B surface antigen; HDL-C: High density lipoprotein.
