Table summarizes the inter-observer variability of two pathologists whose opinions were taken into consideration during this study (383 cases as shown in Table 2). Sample number was rounded off to 380 for statistical comparison between the two groups. Kappa statistics was performed and the value of Kappa  = 0.011 (95% CI: From −0.078 to 0.099) indicating the strength of agreement is considered to be ‘poor’.
