Spirometry pattern and DLco at initial and final follow-up in HDLI survivors. Figures show changes in the proportion of the spirometric pattern (a) and severity of corrected DLco (b) between the initial and final tests in HDLI survivors. In panel A, 81 and 50 children underwent spirometry at the 1st and 5th follow-ups, respectively. Participants showed the tendency to change to a restrictive pattern. In panel B, 81 and 43 children underwent DLco at the 1st and 5th follow-up, respectively. Most participants showed persistent decline in the diffusion defect, although some showed improvement
