† BMI, body-mass index; the BMI is the weight kilograms divided by the square of the height in meters. * 35 patients received oxygen supply only, two patients were treated with non-invasive ventilation, and 16 with invasive ventilation. Disease severity was graded according to intensity of treatment: mild = ambulatory treatment; moderate = hospital treatment; severe = inward treatment with respiratory (oxygen) supply or treatment at the intensive care unit (ICU) with non-invasive or invasive ventilation; PTH = parathyroid hormone; CRP = C-reactive protein; IL-6 = interleukin 6; data are depicted as mean ± SD, p-values were calculated with Kruskal–Wallis Test.
