Long-Term Burden of BPD and Health-Related Quality of Life (BronQ Family)

"A unified questionnaire will be utilized for all participants, irrespective of their group assignment. Participants will be assigned to the BPD or comparison group retrospectively, based on their answers defining the BPD-status. To enhance comprehension, the questionnaire avoids using the term BPD wherever feasible and instead employs a more general reference to lung problems."
