TG and Stroke: Based on the results of repeated measures ANOVA, T3 levels as well as cognitive levels were statistically different in the rTMS group compared to the Sham group, both at post-intervention and at follow-up (P < 0.05), our study also investigated whether changes in cognitive function scores observed after rTMS treatment were correlated with equivalent changes in thyroid hormone levels in older stroke patients with low thyroid hormone levels.
