Nonalcoholic Fatty Liver Disease Is Associated with Increased Atrial Fibrillation Risk in an Elderly Chinese Population: A Cross-Sectional Study

Figure 1

Prevalence of AF in an elderly Chinese population stratified by normal or elevated serum liver enzyme concentration. Normal range for AST or AST level: ≤40 U/L; elevated range for AST or ALT level: >40 U/L; normal range for GGT level in male: ≤50 U/L; elevated range for GGT in male: >50 U/L; normal range for GGT level in female: ≤32 U/L; elevated range for GGT in female: >32 U/L. P value <0.001/=0.004/<0.001 by the χ2 test in AST/ALT/GGT group.
