Adjusted means and mean differences (95% confidence interval) of regional cortical thickness between 1.5 T and 3 T for females in the age group 41–55 after controlling for confounding effects.

Note: overall field strength effect on regional cortical thickness is significant with p-value <0.0001 using Pillai's Trace test; Factors ajusted for include: age, gender, resolution, scanner type, sequence, and interactions of field*age, and field*gender. +STS = superior temporal sulcus.
