Assessment of liver stiffness measurement-related markers in predicting liver-related events in viral cirrhosis with clinically significant portal hypertension

Figure 2 Proportional hazard hypothesis test and risk stratification analysis. A: The risk stratification diagram in the training cohort; B: The Schoenfeld residual diagram of liver stiffness measurement (LSM), LSM-albumin ratio (LAR), and LSM-platelet ratio (LPR) in the training cohort; C: The risk stratification diagram in the validation cohort; D: The Schoenfeld residual diagram of LSM, LAR, and LPR in the validation cohort. The horizontal axis represents the follow-up time (days), the vertical axis represents the cox regression coefficient of the models, and the solid line and the dotted line represent the fitted spline smooth curve and the standard deviation (confidence interval) of 2 units above and below the fitted curve, respectively.
