POSTN and tick-borne encephalitis: Analyses between serum biomarkers and the extent of an individual area on HRCT showed that monomeric and total periostin had a significant negative correlation with the extent of normal lung area (r = −0.57 and −0.62) and a positive correlation with the extent of honeycombing (r = 0.54 and 0.65), reticulation (r = 0.51 and 0.78), fibrosis score (r = 0.55 and 0.78), and TBE grade (r = 0.47 and 0.70), but not GGA, airspace consolidation, and inflammation score.
