As depicted in Figure 2, comparison between cancer and normal tissues did not reveal statistically significant differences in HERV-H (1.00, 95% CI: 0.82–1.22 vs. 1.00, 95% CI: 0.66–1.53; p > 0.05), HERV-K (HML-2) (1.00, 95% CI: 0.81–1.24 vs. 1.00, 95% CI: 0.76–1.32; p > 0.05), or HERV-P (1.00, 95% CI: 0.72–1.40 vs. 1.01, 95% CI: 0.64–1.61; p > 0.05) env gene or HERV-K (HML-2) pol (0.96, 95% CI: 0.66–1.40 vs. 1.03, 95% CI: 0.64–1.65; p > 0.05) gene geometric mean transcription levels. The gene discussed is ERVW-1; the disease is cancer.
