Correlations between BMI and frontal P300a latency were calculated separately for the CP− and CP+ groups. The results of this analysis validated the results shown in the previous ANOVA. BMI was not associated with a change in frontal P300a latency among CP− subjects (r = .09, p =.11). However, among subjects compromised by a childhood history of conduct problems, an increase in BMI occasioned an increase in frontal P300a latency (r = .31, p = .01).
