• Maternal TSH serves as an accessible proxy for thyroid function and its downstream effects on fetal growth. — Association between age-specific preconception thyroid-stimulating hormone (TSH) and birth weight: a retrospective study
• A significant non-linear (U-shaped) association between preconception TSH and both LGA and AGA was identified exclusively in women aged 20–24 years. — Association between age-specific preconception thyroid-stimulating hormone (TSH) and birth weight: a retrospective study
• The TSH level associated with the lowest odds ratio for LGA was 1.62 mIU/L in the 20–24 age group. — Association between age-specific preconception thyroid-stimulating hormone (TSH) and birth weight: a retrospective study
• Both low and high preconception TSH were associated with significantly increased LGA risk and reduced AGA likelihood compared to the reference range. — Association between age-specific preconception thyroid-stimulating hormone (TSH) and birth weight: a retrospective study
• No statistically significant association between preconception TSH and LGA, SGA, or AGA was found in women aged 25–39 across all TSH ranges tested. — Association between age-specific preconception thyroid-stimulating hormone (TSH) and birth weight: a retrospective study
• The TSH–birth weight relationship is age-dependent and does not generalise to women aged 25–39. — Association between age-specific preconception thyroid-stimulating hormone (TSH) and birth weight: a retrospective study
