2. Figure 1
Representative plots for single-nucleotide polymorphism analysis by triplex high-resolution melting (HRM) assay. A: Typical normalized melting peaks for the three amplicons included in the multiplex genotyping assay. Detailed analysis by sequencing and high-resolution melting for RNF7 rs B: Representative Sanger sequencing traces for the three rs genotypes: AA, AC, and CC (the rs polymorphism site on all traces is highlighted by the rectangle). C: Nonnormalized melting curves and placement of normalization intervals for rs (the premelt region considered for normalization is delimited by the blue vertical lines, and the post-melt region is delimited by the two red vertical lines). D–G: HRM data transformation by the two methods available in the instrument software: relative fluorescence unit (RFU) difference, consisting of normalization of melting curves (D), followed by RFU difference clustering (E); and dF/dT difference clustering, consisting of calculation of the negatively transformed first derivative of the normalized melting curves (F), followed by dF/dT difference clustering (G).

Performance of a predictive model based on triplex single-nucleotide polymorphism (SNP) genotyping data for advanced fibrosis (METAVIR F3 to F4) in chronic hepatitis C patients. A: Validation plot of the model: correspondence between the predicted and observed probability for the presence of advanced fibrosis. Triangles and whiskers represent the observed frequencies and the corresponding 95% CIs, by deciles of predicted probabilities. Bottom of the graph: Spikes show the distribution of the patients according to the predicted probability of advanced fibrosis, stratified by the actual fibrosis stage: advanced fibrosis (F3 to F4) above the x axis and absence of advanced fibrosis (F0 to F2) below the x axis. B: Predicted probabilities in patients with and without advanced fibrosis. Boxplots showing the medians (solid horizontal lines), interquartile ranges (boxes), and minimum-maximum ranges (whiskers); means are shown as solid dots. The discrimination slope of the predictive model for advanced fibrosis was C and D: Receiver operating characteristic (ROC) curve (C) and decision curve analysis (D) of the predictive model, including or not including the genotyping information of the three SNPs.

4. Figure 3
Performance of the model based on triplex single-nucleotide polymorphism (SNP) genotyping data for the prediction of sustained virological response (SVR) achievement with pegylated interferon plus ribavirin combination treatment in chronic hepatitis C patients. A: Validation plot of the model: correspondence between the predicted and observed probability of SVR. Triangles and whiskers represent the observed frequencies and the corresponding 95% CIs, by deciles of predicted probabilities. Bottom of the graph: spikes show the distribution of the patients according to the predicted probability of SVR, stratified by outcome: SVR above the x axis, and no SVR below the x axis. B: Predicted probabilities in patients with and without SVR. Boxplots showing the medians (solid horizontal lines), interquartile ranges (boxes), and minimum-maximum ranges (whiskers); means are shown as solid dots. The discrimination slope of the predictive model for SVR was C: Receiver operating characteristic (ROC) curve with true-positive and false-positive rates plotted for the decision thresholds discussed in the text. D: Decision curve analysis of the predictive model, including or not including IFNL3 or genotyping information of the three SNPs.
