Correlation between baseline selenium level and change in Clinical Activity Score (CAS). A scatterplot showing the relationship between baseline serum selenium concentration (µg/L) and the change in CAS (ΔCAS) from baseline (FU0) to 2 months after treatment completion (FU3) in patients with thyroid eye disease receiving intravenous steroid therapy. A significant inverse correlation was observed (Spearman ρ = − 0.308, p = 0.047), suggesting that higher baseline selenium levels were associated with greater CAS improvement. A red loess curve was fitted to illustrate the trend.
