The impact of time to bronchiolitis obliterans syndrome (BOS) onset on survival after the onset of BOS among 95 bilateral lung transplant recipients. Early-onset BOS (onset within 2 yr of lung transplant), occurring in 34% (32/95) of patients, was associated with significantly increased mortality as compared with late onset (P = 0.04; hazard ratio, 1.84; 95% CI, 1.03–3.29). Four-year Kaplan-Meier survival estimates after BOS for the early-onset group were 24% in contrast with 32% in the late-onset group; P = 0.04.
