Table 3 Comparison of lung cancer frequency, stage, and cause of mortality according to presence pleural plaques. The table includes events from the entire period of lung cancer screening (median follow-up 9.5 years). Notably, pleural plaques were searched on baseline LDCT, therefore detection of pleural plaques either preceded (e.g. event at incidence rounds) or was synchronous (e.g. event at baseline round) to each detailed event
