Age-dependent relationship between preoperative serum aminotransferase and mortality after cardiovascular surgery
Figure 3. Kaplan-Meier estimated postoperative 90-day cumulative mortality and adjusted hazard ratios according to the ALT, AST, and De Ritis ratio groups stratified by age. Asterisks indicate the statistical significance. * P<0.05, ** P<0.001. ALT: alanine aminotransferase; AST: aspartate aminotransferase; HR: hazard ratio; CI: confidence interval.
