RUL: Right Upper Lobe, RML: Right Middle Lobe, RLL: Right Lower Lobe, LUL: Left Upper Lobe, LLL: Left Lower Lobe
aFull iPCD cohort that participated in the study, excluding lobectomised patients (May 2017)
bDenominator reflects the total number of resected lobes. Some patients had more than one lobe resected. For one patient (one with one lobe resected) the exact site was not reported
