Thus, prognostically favorable signs were a decrease in the concentration of urea below 7.5 mmol/L (OR = 1.921; 95% CI 1.061-4.270; <i>p</i> = 0.0342), a decrease in the area of the absorption band at 2957 cm<sup>-1</sup> below 24 (OR = 3.875; 95% CI 1.160-12.70; <i>p</i> = 0.0003), and an increase in the concentration of cancer antigen CA27.29 above 3 U/L (OR = 2.138; 95% CI 1.021-7.273; <i>p</i> = 0.0343) and CA-15-3 above 39 U/L (OR = 3.896; 95% CI 1.062-14.07; <i>p</i> = 0.0072). The gene discussed is MUC1; the disease is cancer.
