Figure 1. Analysis of the incidence of colorectal CA in groups matched for age range, sex, and CCI, of patients with history of CMV infection versus the control group. CCI: Charlson Comorbidity Index; CMV: cytomegalovirus; CA: cancer.

Figure 2. A notable increase in incidence of colorectal CA in patients not previously infected with CMV (405 patients) in comparison to patients previously infected with CMV (165 patients). CMV: cytomegalovirus; CA: cancer.

Figure 3. Distribution by age of colorectal CA patients in both the CMV(+) and CMV(-) groups. Patients not previously infected show consistently higher volumes of patients with colorectal CA over all ages and both groups peak in the age range 70 - 74. CMV: cytomegalovirus; CA: cancer.

Figure 4. Distribution in incidence of colorectal CA in both the CMV(+) and CMV(-) groups separated by sex. Males display a higher incidence of colorectal CA in both groups. CMV: cytomegalovirus; CA: cancer.

Figure 5. The difference in incidence of colorectal CA in both the CMV(+) and CMV(-) groups separated by region of the USA. Patients located in the southern region display the highest incidence of colorectal CA in both groups. CMV: cytomegalovirus; CA: cancer.

Figure 6. The difference (in days) in length of stay for treatment in both the CMV(+) and CMV(-) groups. The CMV(+) group displays a stay nearly twice as long as the CMV(-) group. CA: cancer; CMV: cytomegalovirus.
