Fig. 1From: Causal relationship between hypothyroidism and temporomandibular disorders: evidence from complementary genetic methodsOverview of the present MR study. (A) Univariable MR analyses to estimate overall effects between thyroid health (hypothyroidism; hyperthyroidism; thyroid-stimulating hormone, TSH; free thyroxine, fT4) and temporomandibular disorders (TMDs); (B) Multivariable MR analyses to estimate direct effects of hypothyroidism of TMDs; (C) Applying the same multivariable framework to estimate the indirect effects on TMDs mediated along the causal pathway via TSH, fT4 or hyperthyroidism. The colored arrows in red and green on these graphs illustrate the causal effect of hypothyroidism on the outcome being estimated in multivariable MR analysesBack to article page
