Fig 11. ROC curves comparing the predictive performance of different combinations of sequence-based diversity measures of HIV gp120-C2-1, gp120-C2_3 and gp120-V3 segments for identifying HIV-1 subtype B infection recency.

Fig 11

Five combinations of sequence-based diversity measures were analyzed: P1, percent complexity; P2, percent diversity; P3, number of haplotypes; P4, Shannon entropy; P5, Shannon entropy+ percent diversity and P6, Number of haplotypes+ percent diversity. Three HIV-1 env segments were considered: gp120-C2_1, gp120- C2_3 and gp120-V3 -. ROC = receiver operating characteristics; AUC = area under the curve. AUC values between 0.8 and 1 were considered performance measures.
