Panels A-D: Raw concentrations (pg/ml) and log-transformed z-scores for CSF dopamine and homovanillic acid by HIV serostatus. Log-transformed z-scores substantially reduced the skewness of biomarker distributions and were accordingly used for parametric analyses. Panel E: Dopamine and homovanillic acid z-scores were positively correlated in both HIV− (r=.39, p<.001) and HIV+ groups (r=.42, p<.001).
