Further analyses included paired t-tests in a subset of 46 patients with schizophrenia who had elevated CRP (n = 23) and normal CRP (n = 23) who were matched within 2 points on BMI to compare performance on any measures that were significantly different between the elevated and normal CRP groups (i.e., WAIS-III IQ and Arithmetic) to control for BMI. Here, CRP is linked to schizophrenia.
