First Test Performed	Frequency	%	Cumulative Frequency	Cumulative %
Guideline-inconsistent care
CT scan-guided biopsy	5,009	32.7	5,009	32.7
Bronchoscopy without TBNA	7,152	46.7	12,161	79.4
Guideline-consistent care
Bronchoscopy with TBNA	1,043	6.8	13,204	86.2
Bronchoscopy with TBNA + EBUS or EUSa	42	0.3	13,246	86.5
Mediastinoscopy alone	874	5.7	14,120	92.2
Mediastinoscopy and thoracotomy	181	1.2	14,301	93.4
Thoracotomy alone	1,015	6.6	15,316	100

EBUS = endobronchial ultrasound; EUS = endoscopic ultrasound; TBNA = transbronchial needle aspiration.

^aStrata with ≤ 10 patients were suppressed as per National Cancer Institute policy and are reported as “ < 11” to ensure confidentiality. Endoscopy with ultrasound was done in < 11 patients and was, therefore, included in the bronchoscopy with TBNA + EBUS category to protect patient confidentiality.
