Ethics approval and consent on the participation Approval No: zn210703. Competing interests The authors declare that they have no competing interests. Authors' contributions TT and NT conceived and designed this study. ME dispensed blood samples for measuring the serum 25(OH)D levels, whereas TT, NT, and TS pretreated blood samples for that. NT measured the serum 25(OH)D levels. TT and TS collected patient data from electronic medical records. TT and NT analyzed data. HI, TH, KT and NM supervised the conduct of this study. TT and NT drafted the manuscript. All authors have substantially contributed to its revision. All authors have read and approved the final manuscript.
