Albumin (ALB) levels <35 g/L were observed in 55.6% (95% CI = 19.1-92.2) of studies, erythrocyte sedimentation rate (ESR)>20 mm/h in 91.4% (95% CI = 69.8-100.0), C-reactive protein (CRP)>6 mg/L in 82.5% (95% CI = 71.1-93.8), anaemia in 59.0% (95% CI = 38.1-79.8), CD4+ T cell count ≤50 pieces/μL in 70.3% (95% CI = 57.5-81.7), CD4+ T cell count 51-200 pieces/μL in 22.1% (95% CI = 14.8-30.3), and CD4+ T cell count >200 pieces/μL in 4.6% (95% CI = 0.8-10.3) (Table 4 and Table 5). This evidence concerns the gene ALB and anemia.
