Figure 4.

Correlations between the amount of GPC1+ cells ($n$), $n/V$ ($V$, volume of urine sample), $n/N$ ($N$, total number of cells in urine sample) and conventional clinicopathological parameters of the PCa–prostate specific antigen (PSA) level and Gleason score (GS). The lowest correlation was identified between $n$ and PSA level, and the highest correlation was identified between $n/N$ and GS.
