Figure 2. Screening for prognosis-related PRGs and LASSO regression. (A) Forest plot of the prognosis-related PRGs based on P < 0.05. Red and green indicate high and low risk, respectively. (B) LASSO coefficients for PRGs. Each curve represents a PRGs. (C) 1,000-fold cross-validation of variable selection in LASSO regressions by 1-SE criteria. PRGs, Pyroptosis-related genes. LASSO, Least absolute shrinkage and selection operator.
