Figure 1 shows that although patients with p16-negative tumours tended to have longer survival times, the statistical analysis using the Mann–Whitney U test (p = 0.74, Z-score: −0.34) did not find a significant difference in survival times between the two groups. Additionally, although there were slightly larger tumour sizes in p16-negative cases, this difference was not statistically significant according to the Mann–Whitney U test (p = 0.21, Z-score: 1.23). The gene discussed is CDKN2A; the disease is neoplasm.
