Table 3 Statistical analysis

From: Stereotactic body radiation therapy (SBRT) for lung malignancies: preliminary toxicity results using a flattening filter-free linear accelerator operating at 2400 monitor units per minute

  Acute toxicity (≤ 90 days) Late toxicity (>90 days)
Clinical factor OR 95% CI OR 95% CI
BED10 0.98 0.95-1.01 0.98 0.95-1.01
Tumor size 0.97 0.46-2.08 1.47 0.86-2.51
Number of fractions 2.90 0.75-11.2 1.90 0.14-2.27
Tumor location 0.53 0.10-2.85 0.56 0.14-2.27
  1. Four clinical factors predicted to influence risk of pulmonary toxicity were analyzed using logistical regression. BED10, tumor size, and number of fractions were analyzed as continuous variables and tumor location was analyzed as a dichotomous variable (Central vs peripheral).
