| Evaluation | Mean ± SD | Median (IQR) | Mean ± SD | Median (IQR) | Mean ± SD | Median (IQR) |
| Guideline consistent, mediastinal sampling done first | 1.4 ± 0.7 | 1a (1-2) | 1.3 ± 0.7 | 1a (1-2) | 1.4 ± 0.7 | 1a (1-2) |
| Guideline inconsistent, NSCLC present, mediastinal sampling performed second or later | 2.5 ± 0.8 | 2a (2-3) | 2.5 ± 0.8 | 2a (2-3) | 2.5 ± 0.8 | 2a (2-3) |
| Guideline inconsistent, NSCLC present, mediastinal sampling not done | 1.3 ± 0.6 | 1 (1-2) | 1.4 ± 0.7 | 1 (1-2) | 1.3 ± 0.6 | 1 (1-2) |
| Guideline inconsistent, small cell lung cancer present | 1.4 ± 0.7 | 1 (1-2) | 1.4 ± 0.7 | 1 (1-2) | 1.4 ± 0.7 | 1 (1-2) |
IQR = interquartile range. See Table 1 legend for expansion of other abbreviations.
