Additionally, significant differences are observed in thyroid hormone levels: mean FT3 levels decrease from 4.58 ± 0.57 pmol/L in mild SCH to 4.00 ± 0.49 pmol/L in severe SCH (p < 0.001) and mean FT4 levels decline from 14.86 ± 2.12 pmol/L to 13.23 ± 1.52 pmol/L across the same groups (p = 0.002). Here, TG is linked to spindle cell hemangioma.
