Predicting risk of post-hepatectomy liver failure in patients undergoing liver resection with controlled low central venous pressure

Figure 2 Application of least absolute shrinkage and selection operator regression analysis for predictor variable selection. A: The least absolute shrinkage and selection operator coefficient trajectory path diagram, where each line represents the coefficient trajectory of an independent variable; B: The cross-validation curve for least absolute shrinkage and selection operator regression analysis, with the dashed line on the left indicating the log (λ) value corresponding to the minimum mean-square error. By selecting log (λ) at the minimum mean-square error, five variables with non-zero coefficients were identified.
