  1. The calculations of differences between individuals with and without lesions are based on ANCOVA Least Square Mean regression analyses normalising for age. *: individuals with lesions higher in mercury levels than individuals without lesions. **: individuals with lesions lower in mercury levels than individuals without lesions.
