Figure 1: Boxplot of time taken per slide of parathyroid frozen sections reviewed by three pathologists through three systems (n = 76). As the data showed large variance in some groups, a logarithmic transformation of the data was applied before the repeated measures analysis of variance and post hoc tests. (The dark line in the middle of the boxes is the median of the values of time taken. The small circles (○) represent the outliers with values more than 1.5 × interquartile range. The asterisks (*) are extreme outliers with values more than 3 × interquartile range. ^{†}Another pathologist (Pathologist 4) instead of Pathologist 2 interpreted all the 76 slides through Aperio LV1.) s, seconds; PG, Pathologist; IQR: interquartile range
