Mucin and phospholipids determine viscosity of gallbladder bile in patients with gallstones

Table 2 Correlation coefficients between viscosity and mucin, protein, lipids and CSI in gallbladder bile of 36 patients with cholesterol or mixed gallstones

Viscosity (mPa·s)	Correlation coefficient (r)	Significance level
Mucin (g/L)	0.645	P < 0.001
Total protein (g/L)	0.201	P = 0.24
Total lipids (g/dL)	0.238	P = 0.16
Cholesterol ( mmol/L)	0.223	P = 0.19
Phospholipids ( mmol/L)	0.344	P = 0.04
Bile acids ( mmol/L)	0.161	P = 0.34
CSI	-0.141	P = 0.41
