Table 9 Comparison of laboratory values at 20–24 weeks vs. 36 weeks gestation among HIV-uninfected women

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 Number of Pairs Mean (*) of the paired differences 95% CI p value*

Total T lymphocytes as a % of all lymphocytes 19 1.1 -3.1 5.2 0.6
  1. (*) For each pair, the 20–24 week laboratory value is subtracted from the 36 week value. Hence, a negative value indicates a decrease over time in the laboratory parameter.
