Causal Influence of Thyroid Function on Lipid Profiles. This figure demonstrates the effects of thyroid function on lipid profiles. An increase in FT4 is associated with higher levels of apoA-I and HDL, while a rise in TSH correlates with increased apoB levels. Notably, in this figure, asterisks indicate the level of statistical significance: a single asterisk (*) denotes a P-value less than 0.05, and double asterisks (**) denote a P-value less than 0.01.
