Unless otherwise specified, data are numbers of patients (with percentages in parentheses). *Data are median (with IQR in parentheses). aPTT = activated partial thromboplastin time, CBCT = cone-beam computed tomography, IQR = interquartile range, PT INR = prothrombin time-to-international normalized ratio, PTNB = percutaneous transthoracic needle biopsy
