|---|---|---|---|---|
| Variable | HR (95% CI) | P-value | HR (95% CI) | P-value |
| SII in GCTs | 1.6404 | 0.1337 | 2.6502 | 0.0200 |
| High vs low | (0.8590–3.1324) | (1.1656–6.0256) | ||

| Poor vs intermediate/good risk | (4.0501–13.9645) | (3.3483–14.0819) | ||
Abbreviations: CI=confidence interval; GCT=germ-cell tumour; HR=hazard ratio; IGCCCG=International Germ Cell Cancer Collaborative Group; OS=overall survival; PFS=progression-free survival; SII=systemic immune-inflammation index.
