Resting heart rate causally affects the brain cortical structure: Mendelian randomization study.

To take into account multiple testing for different regions, the associations with P -values below 1.84 × 10 −4 ( α = 0.05/272 outcomes) were regarded significant associations after Bonferroni correction and associations with P- values below 0.05 but above 1.84 × 10 −4 were deemed as nominally significant.
