Kaplan-Meier survival estimates at 6-month landmark after bronchiolitis obliterans syndrome (BOS) diagnosis, stratified by tertiles of FVC percent predicted values for the entire cohort (n = 75): upper tertile, greater than 77.5% (black line); middle tertile, 67–77.5% (blue line); and lower tertile, less than 67% (red line). The comparisons are lowest versus highest, hazard ratio (HR) of 2.31 (95% confidence interval [CI], 1.0–5.7; P = 0.06); lowest versus middle, HR of 2.40 (95% CI, 1.0–5.6; P = 0.04); and lowest versus middle/highest, HR of 2.36 (95% CI, 1.2–4.8; P = 0.02).
