Spearman correlation coefficients (r’) obtained between the different variables of microradiography, FTIRM and indentation in: Part 2A: All samples (juvenile and adult bone) with pooled osteonal, interstitial, (*p < 0.05, **p < 0.01); Part 2B: Juvenile bone with pooled osteonal and interstitial, (*p < 0.05, **p < 0.01, BL: borderline 0.05 < p < 0.07); Part 2C: Adult bone with pooled osteonal and interstitial, (*p < 0.05, **p < 0.01).
