25-hydroxy-vitamin D levels in mildly-symptomatic COVID-19 patients, in severely-symptomatic COVID-19 patients and in matched non SARS-CoV-2 infected control subjects. Legend: Data are shown as mean 25-hydroxy-vitamin D values and their 95% confidence interval Tukey method is used to control the inflation of type I error due to head to head comparisonsP-value: SARS-CoV-2 infected control subjects vs mildly-symptomatic COVID-19 patients 0.006, SARS-CoV-2 infected control subjects vs severely-symptomatic COVID-19 patients < 0.0001, mildly-symptomatic COVID-19 patients vs severely-symptomatic COVID-19 patients < 0.0001
