The RCS model established the relationship between individual essential trace metals and rTL in the 30–59 years old population. The shaded area represents the confidence interval, while the P-value indicates the strength of the correlation. In the plots where the line slopes upwards, it indicates a positive correlation between the metal and rTL. This means that as the metal concentration increases, the telomere length (rTL) also increases. In the plots where the line slopes downwards, it indicates a negative correlation between the metal and rTL. This means that as the metal concentration increases, the telomere length (rTL) decreases.Models were adjusted for smoke, drink, sex, age, ethnic, education, overweight and fat.
