Image analysis results of the PCNA immunohistochemistry in stroma, glandular epithelium (GE) and luminal epithelium (LE). Box and whisker plots representing the median value with 50% of all data falling within the box. The whiskers extend to the 5th and 95th percentiles. In the control group (OVX) and ICI treated group n = 4, in the other groups n = 5. Values with different letter designations are significantly different (p < 0.05).
