The observation of lower mortality rates at lower degrees of latitude, along with other preliminary reports on the association between serum levels of 25OHD and the risk of having the disease or a critical outcome, have suggested that vitamin D could modulate the risk and mitigate the severity of COVID-19 [1, 2, 5] . Therefore, we aimed to evaluate whether vitamin 25OHD supplementation, which may be a better surrogate of real 25OHD status, is associated with prognosis in COVID-19 patients from the Italian outbreak area of Lombardy. Further studies are needed to clarify the role of vitamin D supplementation and status in modulating the severity of COVID-19, as well as its prevention. ./cache/cord-321817-z9oj9nmv.txt ./txt/cord-321817-z9oj9nmv.txt
