Table 12 Comparison of laboratory values at birth vs. 4–6 weeks of age among HIV-infected and HIV-uninfected infants

From: Selected hematologic and biochemical measurements in African HIV-infected and uninfected pregnant women and their infants: the HIV Prevention Trials Network 024 protocol

Laboratory Parameter HIV-infected Infants HIV-uninfected Infants p value
  Number of Pairs Mean (*) of the paired differences 95% CI Number of Pairs Mean (*) of the paired differences 95% CI  
    Lower Upper    Lower Upper  
Hemoglobin g/dl 124 -7.1 -7.8 -6.4 1301 -7.0 -7.2 -6.8 < 0.0001
Hematocrit % 124 -21.0 -23.0 -19.0 1298 -20.9 -21.6 -20.3 < 0.0001
Platelets 103/μL 122 89.2 64.0 114.5 1292 125.1 115.9 134.3 < 0.0001
White blood cell count 103/μL 119 -2.0 -3.4 0.5 1263 -4.8 -5.2 -4.5 0.009
  1. (*) For each pair, the birth laboratory value is subtracted from the 4–6 week value. Hence a negative value indicates a decrease over time in the laboratory parameter.
