Table 1. Demographic and neuropsychological information for controls and schizophrenia patients.

Demographics and neuropsychological testing scores for controls and schizophrenia patients. There were no significant differences in mean age, years of education, or premorbid IQ (HART FSIQ), as measured by independent sample t-tests. As measured by Fisher’s exact test, patients and controls were equally likely to be male or female and smokers or non-smokers. MOCA scores were significantly lower in patients than controls (p = 0.003). Data are presented as mean (standard deviation). A cutoff of p < 0.05 was used for significance.

	Control	Patient	p - Value
Male/Female	20/4	19/5	n.s.
Age (y)	36.6 (14.6)	37.5 (16.7)	n.s.
Education (y)	12.7 (1.5)	12.6 (1.7)	n.s.
Smoker/Non-smoker	9/15	14/10	n.s.
MOCA	26 (3.3)	23.1 (3.2)	0.003
HART FSIQ	103.6 (9.8)	100.4 (8.8)	n.s.
