Patients
Sixty children/adolescents of Sub-Saharan African or Caribbean ethnicity
were prospectively included in the DrepaSympa trial.5Among them, 43 had subsequent PFTs as part of their routine follow-up
(without DLNO measurement). These 43 participants are described in this
retrospective study and the 17 non-included children are described in
the online supplement. This study was approved by our local Ethics
Committee (PHENOBS: N° 2018‐430). The parents were informed of the
collection of the prospective data for research purposes and they could
request that their child be exempted from this study in accordance with
French law (non-interventional observational research).
