Variables Associated with Malignancy after Multivariate Analysis

VariableOdds ratioLower 95% CIUpper 95% CI
SUV max: increase in odds of malignancy per unit elevated SUV max1.541.162.05
Purity: reduced odds of malignancy if pure0.080.030.22
  • SUV max, purity, primary site, and percentage symmetry were evaluated as potential predictors of malignancy. Both forward- and backward-selection model building yielded SUV max and purity as significant predictors of malignancy. Other indicators did not significantly improve model fit.
