Randomisation was stratified according to the presence of mediastinal lymph nodes measuring 1 cm or more in the short axis and by recruiting centre. We used a telephone randomisation method with permuted blocks of four generated by a computer. Because of the nature of the intervention, masking of participants and consenting investigators was not possible.

Two patients from the EBUS-TBNA group underwent EUS-FNA. The median time to treatment decision was shorter with EBUS-TBNA (14 days; 95% CI 14-15) than with CDS (29 days; 23-35) resulting in a hazard ratio of 1·98, (1·39-2·82, p<0·0001). One patient in each group had a pneumothorax from a CT-guided biopsy sample; the patient from the CDS group needed intercostal drainage and was admitted to hospital.</span></span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif; line-height: 17.9998016357422px;"><span style="font-size: 8pt;"><span style="font-family: Arial;">INTERPRETATION:</span></span></h4><p style="margin: 0px 0px 0.5em; font-family: arial, helvetica, clean, sans-serif; font-size: 13px; line-height: 17.9998016357422px;"><span style="font-family: Arial;"><span style="font-size: 8pt;"><span class="highlight">Transbronchial</span> <span class="highlight">needle</span> <span class="highlight">aspiration</span> guided by <span class="highlight">endobronchial</span> ultrasound should be considered as the initial investigation for patients with suspected <span class="highlight">lung</span> <span class="highlight">cancer</span>, because it reduces the time to treatment decision <span class="highlight">compared</span> with <span class="highlight">conventional</span> <span class="highlight">diagnosis</span> and <span class="highlight">staging</span>techniques.</span></span></p&gt
