Table 1 Clinical, biochemical characteristics and radiation planning parameters of patients enrolled in this study

From: Biologically effective dose (BED) of stereotactic body radiation therapy (SBRT) was an important factor of therapeutic efficacy in patients with hepatocellular carcinoma (≤5 cm)
