Using BAL CXCL9 concentrations cutoffs.

	Univariable		Multivariable ƚ
	HR (95% CI)	p-value	HR (95% CI)	p-value
OP	1.55 (1.13–2.12)	0.007	1.34 (0.97–1.86)	0.077

OP with CXCL9 > 50th%	2.19 (1.42–3.35)	0.001	1.90 (1.22–2.94)	0.010
OP with CXCL9 > 75th%	2.32 (1.37–3.92)	0.002	1.83 (1.06–3.16)	0.031

Definition of abbreviations: CLAD = chronic lung allograft dysfunction; HR = hazards ratio;CI = confidence interval; OP = organizing pneumonia; % = percentile.

^ƚ Multivariable model adjusted for diffuse alveolar damage, acute rejection, and lymphocytic bronchiolitis.
