Comparisons of the performance of each model using receiver operating characteristic (ROC) analysis in the training set (A) and testing set (B). LA, linoleic acid; GLA, gamma-linolenic acid; EDA, eicosadienoic acid; DGLA, dihomo-gamma-linolenic acid; AA, arachidonic acid; PUFA, polyunsaturated fatty acid; PC, principal component. Model 1: LA/total n-3 PUFAs + systolic BP + duration of diabetes; Model 2: GLA/total n-3 PUFAs + systolic BP + duration of diabetes; Model 3: EDA/total n-3 PUFAs + systolic BP + duration of diabetes; Model 4: DGLA/total n-3 PUFAs + systolic BP + duration of diabetes; Model 5: AA/total n-3 PUFAs + systolic BP + duration of diabetes; Model 6: the 1st PC + the 2nd PC + systolic BP + duration of diabetes; Model 7: Total n-6/n-3 PUFAs + systolic BP + duration of diabetes.
