Unadjusted means and mean differences (95% confidence interval) of regional cortical thickness by field strength (1.5 T vs. 3 T) for right and left hemispheres in 295 controls using multivariate regression model.

The regions with the significant field strength effect (p<0.05) on cortical thickness are denoted with “*”.
Note: overall field strength effect on regional cortical thickness is significant with p-value <0.0001 using Pillai's Trace test. +STS  =  superior temporal sulcus.
