Fig. 1From: A pilot investigation of the association between HIV-1 Vpr amino acid sequence diversity and the tryptophan-kynurenine pathway as a potential mechanism for neurocognitive impairmentScatter plot depicting the Pearson correlation between QUIN and immune marker levels. (A-E) correspond to the Pearson correlation within the Vpr 41 group and (F-J) correspond to the Pearson correlation within the Vpr 55 group. QUIN levels: PPM = ug/mL. Back to article page
