[Retracted] Analysis on the Effects of CT- and Ultrasound-Guided Percutaneous Transthoracic Needle Biopsy Combined with Serum CA125 and CEA on the Diagnosis of Lung Cancer

Figure 2

Comparison of CEA levels between the lung cancer and the benign group ( ±s, ng/ml). The abscissa represents the lung cancer group (n = 94) and benign group (n = 26), while the ordinate represents the CEA level (ng/ml). The CEA levels were (14.05 ± 2.89) ng/ml in the lung cancer group and (3.56 ± 0.89) ng/ml in the benign group. .
