Signature based on molecular subtypes of deoxyribonucleic acid methylation predicts overall survival in gastric cancer

Figure 6 Selection of the prognostic methylation sites for gastric cancer patients by least absolute shrinkage and selection operator analysis. A: The changing trajectory of each independent variable. The horizontal axis represents the log value of the independent variable lambda and the vertical axis represents the coefficient of the independent variable; B: Confidence intervals for each lambda. The optimal values of the penalty parameter lambda were determined by ten-fold cross-validation.
