ALB and cancer: After multivariable adjustment for potential confounders (age, gender, education level, income, coal dust exposure, concentration of CRP, BMI, frequency of smoking, frequency of alcohol drinking, and HBsAg infection status), participants with higher serum albumin levels were at decreased cancer risk of 9%–27%, compared with those whose serum albumin concentrations were below 44.6 g/L (Q2 vs. Q1: HR 0.91, 95% CI 0.78–1.07; Q3 vs. Q1: HR 0.80, 95% CI 0.70–0.92; Q4 vs. Q1: HR 0.73, 95% CI 0.63–0.85).
