Relationship between nodule count and lung cancer probability in baseline CT lung cancer screening: The NELSON study

To explore the relationship between nodule count and lung cancer probability in baseline low-dose CT lung cancer screening.Included were participants from the NELSON trial with at least one baseline nodule (3392 participants [45% of screen-group], 7258 nodules). We determined nodule count per participant. Malignancy was confirmed by histology. Nodules not diagnosed as screen-detected or interval cancer until the end of the fourth screening round...
