Figure 4. Classification of scores of intratubular contamination observed in the confocal laser scanning microscopy (CLSM) images, performed by three examiners (A×C, p=0.015) (B×C, p=0.022). The symbol ** shows the statistical difference between groups B and C (p<0.05), and the symbol *** shows the statistical difference between groups A and C (p<0.01).
