Fig. 7 — Changes in eNO, in eCO, and in the slope of the alveolar plateau for helium (S_he) over time in one transplant recipient. The continuous lines indicate the confidence interval. Note that values of S_he become abnormal before BOS 0-p, and then increase progressively with the BOS stage; in contrast, values of eNO and eCO are much more variable between successive measurements and do not show a consistent trend as BOS progresses.
