Prediction of collagen orientation angle in the superficial zone with a generalized model (a) and with the three condition-specific models (b). The average smoothed spectra of ICRS0, ICRS1 and ICRS2 (c) with the selected wavelengths (black regions) of IVS for each condition-specific model of superficial collagen orientation angle. Furthermore, differences in the spectra of the ICRS groups are highlighted in the 2nd derivative average spectra (y-axes not in scale) within the mutual wavelength regions (I-IV).
