Correlation analysis: in the HIV infection group, significant correlation was noted with LVH and the following variable; BMI for age r= 0.19, CI = (0.11, 0.32), duration of treatment r = -0.49, CI = (-0.33, 0.55), diastolic blood pressure r = -0.38, CI = (-0.20, 0.65), CD4+ cell count r = 0.08, CI = (- 0.01, 0.12), and pulse rate r = -0.13, CI = (0.10, 0.19) (Table 2). This evidence concerns the gene CD4 and HIV infectious disease.
