From: Association of serum copper, zinc and copper to zinc ratio in patients with acute myeloid leukemia

Scatter plots depicting relationships between blast percentages and serum copper (Cu), zinc (Zn), and serum Cu/Zn ratio (SCZR) in AML patients and healthy controls. (A–C) Inverse correlations were observed between Cu and Zn and between Zn and SCZR, while a direct correlation was identified between Cu and SCZR. (D–F) Similar inverse relationships were noted between Cu and Zn and Zn and SCZR, with a positive correlation between Cu and SCZR. (G–I) Blast counts demonstrated a direct correlation with Cu levels (G) and SCZR, but an inverse association with Zn concentrations.
