Does previous asbestos exposure increase the risk of a post coronary artery bypass graft (CABG) pleural effusion – a routine data study?

Table 5 Association between asbestos exposure and post-CABG effusion (J92.0 and J61 codes only)

Outcome 1: Pleural effusion diagnosis or procedure in 30 days to 1 year after CABG	OR (95% CI)	p-value
Crude model	2.27 (1.64, 3.16)	< 0.001
Adjusted model (age, sex, IMD, CCI, CABG codes)	1.63 (1.17, 2.28)	0.01
Outcome 2: Pleural effusion procedure in 30 days to 1 year after CABG	OR (95% CI)
