Abbreviations: CI=confidence interval; CRP=C-reactive protein; HR=hazard ratio; IGCCCG=International Germ Cell Cancer Collaborative Group; IQR=interquartile range; NLR=neutrophils-to-lymphocytes ratio; PLR=platelets-to-lymphocytes ratio; SII=systemic immune-inflammation index.

After log10 transformation: the HR thus corresponds to a 10-fold increase of the variable, bold P-values indicate statistical significance.
