(a) Relative risk of death (hazard ratio) after lung transplant compared to non-OLD controls^a and (b) relative risk of death compared to other fibrotic lung disease controls

	All OLD	Silicosis	Non-silicosis OLD
(a)
Time since transplant
0–1 year	2.3 (1.3–4.4)*	1.0 (0.3–4.1)	3.1 (1.5–6.6)**
>1 year	0.2 (0.03–1.6)	0.4 (0.1–3.0)	0.5 (0.1–3.6)
(b)
0–1 year	2.3 (1.2–4.5)*	1.1 (0.3–4.5)	3.3 (1.5–7.1)**
>1 year	0.5 (0.1–2.0)	0.5 (0.1–3.3)	0.5 (0.1–3.7)

LAS, lung allocation score; OLD, occupational lung disease.

^aAdjusted for recipient age, FEV₁, BMI, LAS, donor age, transplant type (single versus bilateral) and ischaemic time. A hazard ratio of >1.0 represents greater risk for death for subjects who underwent LT for OLD compared with non-OLDs.

*P < 0.05; **P < 0.01.
