The Influence of Cigarette Smoke Exposure on the Copper Concentration in the Serum Depending on the Use of Menopausal Hormone Therapy

Figure 1

Correlation between serum concentration of copper and salivary level of cotinine in MHT users and nonusers (Groups I and II). The vertical line represents salivary cotinine level of 14.0 ng/ml; values ≥14.0 ng/ml correspond to active smoking. Thick lines on this and subsequent graphs represent recommended serum concentrations of copper.
