Normally distributed data were expressed as mean ± SD, using a Student’s t test for comparison. Categorical variables were presented as number (percentage), using the chi-square test or Fisher’s exact test when compared. Differences were considered to indicate significance if a p value was < 0.05
ROSE, rapid on-site evaluation; NSCLC, non small cell lung cancer
