"z" correlation coefficient (?)

Please help to interpret the correlation coefficient specified in this article http://hrcak.srce.hr/file/22665 . They suggest they used Kendall Tau nonparametric correlation, but I can't figure out why it's noted as "z", not "?" ...
"In the group of nonsurvivors, a significant correlation was found between ICP and GCS (z=2.351), and CPP and GCS (z=3.231), while no correlation was observed between MAP and GCS (z=1.287). "
Best Regards, Vlad.
