In univariate analysis, tract embolization (OR = 0.32, CI = 0.17\u20130.61 p<0.001) and nodule size >2\u2009cm (OR = 0.33 CI = 0.14\u20130.8 p = 0.013) had a protective effect on pneumothorax. The puncture path lengths > 2\u201320\u2009mm and >20\u2009mm were risk factors for pneumothorax (OR = 3.35 IC = 1.44\u20138.21 p = 0.006\u2009and OR = 4.36 CI = 1.98\u201310.29 p<0.001, respectively).
