Statistically significant VOCs in the recurrence of UBC in surveillance on Wilcoxon rank-sum testing.
| VOC | CAS number | Relative change in recurrence of UBC (fold change) | Wilcoxon rank-sum P value | Wilcoxon rank-sum false discovery rate |
|---|---|---|---|---|

| 2-ethylhexan-1-ol | 104-76-7 | Decreased (0.424) | P = 6.50 × 10−5 | 1.24 × 10−3 |
| 1,1,4a-trimethyl-4,5,6,7-tetrahydro-3H-naphthalen-2-one | 4668-61-5 | Decreased (0.332) | P = 1.88 × 10−4 | 1.84 × 10−3 |
| 5-ethyl-3-methyloxolan-2-one | 2610-98-2 | Increased (1.426) | P = 7.57 × 10−5 | 1.24 × 10−3 |
| 4-methylpent-3-enoic acid | 504-85-8 | Increased (1.111) | P = 1.01 × 10−3 | 8.29 × 10−3 |
| Heptan-2-one | 110-43-0 | Increased (1.560) | P = 1.44 × 10−4 | 1.77 × 10−3 |
All VOCs were significant in the cancer versus control comparison (bold).
