Nomogram of covariates in model 3 for predicting in-hospital mortality among patients with diabetes who are hospitalised with COVID-19. Upon hospital admission, the risk of mortality for a patient with diabetes can be calculated by computing the corresponding score of points for each of the nine clinical characteristics and then adding them together. Looking at the bottom scale, the probability of in-hospital mortality corresponding to the calculated score can be calculated. LDH, lactate dehydrogenase; Prob, probability; O, oral antidiabetic drugs; I, insulin; O&I, oral antidiabetic drugs and insulin; N, no antidiabetic drugs.
