Table 2 Treatment outcomes and complications at post-transplant 1 year

	WRLD (n = 33)	IPF (n = 91)	P-value
Primary graft dysfunction, n (%)			0.23
Severe	15 (45.5)	38 (41.8)
Non-severe	18 (54.6)	53 (58.2)
Hemothorax, n (%)	10 (30.3)	4 (4.4)	< 0.001
Length of ICU stay, day, median (IQR)	10 (23–7)	9 (5–19)	0.18
Length of hospital stay, day, median (IQR)	31 (49–20)	26 (18–42)	0.24
Pulmonary function tests^a
FVC, %	68.5 ± 19.3	76.6 ± 17.5	0.04
FEV₁, %	62.1 ± 18.6	79.4 ± 16.6	0.001
DLCO, %	61.0 ± 19.7	58.1 ± 17.5	0.57
6MWD, m	518 ± 144	505 ± 106	0.65

DLCO diffusing capacity of the lung for carbon monoxide, FEV1 forced expiratory volume in 1 s, FVC forced vital capacity, 6MWD 6-minute walk distance, WRLD work-related lung disease, IPF idiopathic pulmonary fibrosis, IQR interquartile range. ^aDue to poor physical status and post-transplant complications, some patients did not have pulmonary function tests and the sample size was 26 in the WRLD group and 63 in the IPF group for FVC and FEV₁, and 18 in the WRLD group and 46 in the IPF group for DLCO
