A significant inverse correlation of Gal-3 with DLCO% and KCO% was observed among CLAD-free, while Gal-9 showed inverse correlations with KCO% among stable patients, and with measured FVC in CLAD-BOS patients (the latter with borderline significance, but with a good Rho coefficient: − 0.714, p = 0.058) (Table 2). The gene discussed is LGALS3; the disease is Buschke-Ollendorff syndrome.
