TMT-A = trail making test, part A; BACS-SC = brief assessment of cognition in schizophrenia-symbol coding; WMS-III-SS = Wechsler memory scale-3rd edition-spatial span; HVLT-R = Hopkins verbal learning test-revised; BVMT-R = brief visual-spatial memory test-revised; CPT-IP = continuous performance test-identical pairs. Adjusted F indicates the F value controlled for age, sex, years of education, and BMI.
