A) Correlations between memory z-score and WCST % error: only HIV+ smokers with poorer memory had more errors on the WCST (r=−0.66, p=0.01); the other three groups showed no significant correlations (r= 0.09 to −0.27; p=0.24 to 0.74). B–F): Lower attention z-scores were associated with greater psychopathological symptoms, including obsessive compulsiveness, phobic anxiety, somatization, positive symptom distress index as well as general symptom index.
