A major problem previous has centered around fact that men and women constitute quite different populations, thereby making direct comparisons difficult. Methods.

Results. univariate analysis showed 97,153 carried significantly higher each examined. multivariate stratification had as equally matched in low- medium-risk part spectrum, but high-risk patients, there no difference between Conclusions. Gender predictor except very categories.
