Figure 5.

Bar graphs representing the spectral reflectance percentages (SRPs) of groups H and F. The black bar represents the control cartilage for each group. The SRP₇₀₀ values of groups H and F (left four bars) and SRP₄₇₀ values of groups H and F (right four bars) are shown. Error bars represent the standard deviation of each group. *P < 0.05, group H versus group F; **P < 0.05, versus the control; non-parametric Mann-Whitney U-test.
