(A–C) Patterns of change in stimulated thyroglobulin (sTg) concentration in patients with structural recurrence and sTg1 of (A) 2–4.9 ng/mL, (B) 5–19.9 ng/mL, (C) ≥20 ng/mL. (D) Structural recurrence rate in patients with a ≥50% decrease in sTg and those with a <50% decrease or an increase in sTg. The open dotted lines represent the serial sTg concentrations of each patient, measured every 1 or 2 years until biochemical or structural recurrence. Percent sTg change was defined as the relative change between sTg1 and sTg2.
