Heatmap of urinary heavy metal concentrations. Each row represents an individual subject (grouped as BPH, PL, and PC, and annotated in green, yellow, and red, respectively) and heavy metal concentration values are scaled from − 10 to 10 (blue to red). The data matrix uses a range of colors to represent values, with darker or more intense colors indicating higher values and lighter or less intense colors indicating lower values.
