“…Our random effect models for SMD analysis of serum levels of CD4 + T cells [ 43 , 49 , 55 , 56 , 58 – 62 , 74 , 88 , 91 , 92 ], LDH [ 48 , 55 , 64 , 65 , 88 ], and BDG [ 45 , 55 , 59 , 64 , 92 ] in 12, 5, and 5 studies (respectively), indicated that serum levels of CD4 + T cells (SMD: -0.617; 95% CI:-1.122 to -0.111; I 2 : 95.1%;P = 0.000) and LDH (SMD: -0.089; 95% CI:-0.089 to 0.267; I 2 : 8.2%;P = 0.36) did not differ statistically between HIV/PCP-positive and HIV-positive PCP-negative patients. However, the mean serum and/or BAL levels of BDG of HIV/PCP-positive patients were higher than HIV-positive PCP-negatives (SMD: 2.664; 95% CI:1.110 to 4.217; I 2 : 97.7%;P = 0.000)( Table 2 ).…”
