Potentially toxic mineral elements content in packed red blood cell of ASD patients. (A) Arsenic concentration. (B) Cadmium concentration. (C) Lead concentration. (D) Mercury concentration. (E) Thallium concentration. Potentially toxic mineral elements were measured by Doctor's Data (St. Charles, IL, USA). Green area-reference range. Non-parametric Wilcoxon rank sum test was applied. ASD patients' data were compared to the appropriate reference values—hypothetical median. P < 0.05 were used to indicate statistical significance. **P < 0.01.
