From: A randomised, double-blind, placebo-controlled trial of tropisetron in patients with schizophrenia
Rapid visual information processing (RVP) scores on Cambridge Neuropsychological Test Automated Battery (CANTAB) subtests for non-smoking patients with schizophrenia during treatment placebo and tropisetron. There were significantly different scores for RVP (t = -5.78, degrees of freedom (df) = 11, P < 0.001) in the tropisetron group, but not the placebo group. Data are from the placebo group (n = 12) and the tropisetron group (n = 12).
