Expression levels of LEDGF/p75 versus HIV-1 risk/exposure parameters within different study populations of interest.

*Healthy controls,†HIV-exposed seronegatives. Each HIV-1 risk/exposure parameter (left column) was used to split the study population in two subgroups (a subgroup 1 versus b subgroup 2) based on a categorical or on a numerical parameter. Numerical parameters use median values (see Table 2) to split the study group in two subgroups comparable in size. LEDGF/p75 expression levels are median (interquartile range) values. Within each study population, the P-value (Mann Whitney U) was calculated for each HIV-1 risk/exposure parameter. ND: not determined as none of the subjects used a condom.
