Figure 2 Least absolute shrinkage and selection operator regression-based variable selection. A: Characteristics of variable coefficient changes; B: Selection process for the optimal value of parameter λ in the least absolute shrinkage and selection operator (LASSO) regression model via cross-validation. At λ = 0.0308 (Log λ = -3.4816), LASSO regression identified four significant variables: Age, baseline hepatitis B surface antigen (HBsAg), 12-week HBsAg, and cirrhosis.
