Fig. 1

Comparison between the medians of SERS spectra of serum from H0T (n = 72) and CTR groups (n = 72). Interquartile ranges of the SERS intensity for the two groups are shown as shaded areas. Medians and interquartile ranges were calculated from intensity normalized spectra. The intensity difference between H0T and CTR is reported in the lower part of the figure
