Mann–Whitney rank correlation test of expression of HPV E7 and pRb tumor suppressor proteins in different stages of cervical cancer cases. In the top panel (Early stage I and II) low expression of HPV-E7 protein compared to pRb protein was detected (p-value 0.00058 and < 0.001). However, in advanced stages III and IV, the expression of HPV-E7 protein is significantly higher compared to pRb protein (p-value 0.02 and 0.048 respectively).
