Prediction of CD4 T-Lymphocyte Count Using WHO Clinical Staging among ART-Naïve HIV-Infected Adolescents and Adults in Northern Ethiopia: A Retrospective Study

Table 2

Cross-tabulation of the WHO stages with CD4 T-lymphocyte cell count among ART-naïve HIV-infected adolescents and adults in northern Ethiopia, n = 19525.

WHO stage	CD4 T-lymphocyte count/μl				Total n (%)
	Severe immunosuppression n (%)	Advanced immunosuppression n (%)	Mild immunosuppression n (%)	Not significant immunosuppression n (%)
I	8,750 (90.33)	4,794 (92.23)	2,215 (92.02)	2,070 (92.70)	17,829 (91.31)
II	372 (3.84)	187 (3.60)	114 (4.74)	102 (4.57)	775 (3.97)
III	248 (2.56)	85 (1.63)	45 (1.87)	30 (1.34)	408 (2.09)
IV	317 (3.27)	132 (2.54)	33 (1.37)	31 (1.39)	513 (2.63)
Total	9,687 (100)	5,198 (100)	2,407 (100)	2,233 (100)	19,525 (100)

Severe immunosuppression: <200 CD4 T-lymphocyte cell counts/μl. Advanced immunosuppression: 200–349 CD4 T-lymphocyte cells/μl. Mild immunosuppression: 350–499 CD4 T-lymphocyte cells/μl. Not significant immunosuppression: ≥500 T-lymphocyte cells/μl.
