Perioperative variable selection using a lasso logistic regression model. (A) Dotted vertical lines were depicted at the optimal values byusing the minimum criteria (lambda.min) and 1 SE of the minimum criteria (lambda.1se). (B) Lasso coeffcient profle of 47 vaniables. The coeficient profle is plotted according to the logarithmic sequence. Ten-fold cross-validation via minimum criteria was used to determinrpredictors of model resulted in four features with nonzero coeffcients
