Mean plasma selenium concentrations with 95% C.I. are depicted by severity of wasting and plasma HIV load. Among not-wasted and severely wasted adults, mean plasma selenium concentrations significantly decrease with the increase of plasma HIV load (P = 0.0001 and P = 0.03, respectively). This trend did not reach significance among those with mild and moderate wasting. Among the HIV negative adults, and those in the 1^st and 2^nd tertile of plasma HIV load, mean plasma selenium concentrations significantly decreased with the increasing severity of wasting (P = 0.02, P = 0.008 and P = 0.0001, respectively). This trend did not reach significance among those in the 3^rd tertile of plasma HIV load.
