Fig. 2From: Development of a decision flowchart to identify the patients need high-dose vancomycin in early phase of treatmentFinal decision tree. Final decision tree with three layer and two predictive factors (age and eCCr) is shown. The cut off value for the split is determined by maximizing the LogWorth. G2 value indicates randomness in each subgroup (G2 = 0 means perfect fit). The decision tree analysis revealed that eCCr is the top predictive factor and followed by ageBack to article page
