failed to reach significanceP = 0.141
The inherent variability within specimens showed the best correlation between cyclin A and Ki-67 (Rho 0.409, P = 0.0007), followed by cyclin A and IdUrd (Rho 0.300, P = 0.0152) and finally the correlation between Ki-67 and IdUrd variability failed to reach significance (Rho 0.185, P = 0.141).
