The smooth curve fitting shows the association between the risk of endobronchial biopsy-induced hemorrhage and systolic pressure (a), diastolic pressure (b), mean arterial pressure (c), pulse pressure (d), and pulse pressure to diastolic pressure ratio (e) after adjustment for age, gender, BMI, smoking, lesion locations, cancer histological type and stage, PT, APTT, triglycerides, HDL-C, WBC, platelets, and CRP. Dotted lines represented the upper and lower 95% confidence intervals. BMI, body mass index; PT, prothrombin time; APTT, activated partial thromboplastin time; HDL-C, high-density lipoprotein cholesterol; WBC, white blood cell; CRP, C-reactive protein
