Decreased serum vitamin D level as a prognostic marker in patients with COVID-19

no code implementations25 Dec 2022 Ruyi Qu, Qiuji Yang, Yingying Bi, Jiajing Cheng, Mengna He, Xin Wei, Yiqi Yuan, Yuxin Yang, Jinlong Qin

ROC curve showed the serum vitamin D level could predict the severity classification and prognosis of COVID-19 significantly. Conclusions: Serum 25(OH)D3 level is independently associated with the severity of COVID-19 in elderly, and it could be used as a predictor of the severity of COVID-19.
