Characterization of band ratios as quantifiable spectral markers. Spectra were acquired on frozen tissue sections using a laboratory microscope FTIR (iN10Mx) equipped with an internal infrared source. Analysis were performed from normal livers as controls (n = 11), a alcoholic cirrhosis with their corresponding HCC (n = 10) or b HCV cirrhosis and their corresponding HCC (n = 11) (b). Ratios of two peaks area were calculated and boxplots are shown. Statistical analysis were performed on all patients with unpaired t test (*p < 0.05) or paired t test (^†p < 0.05)
