nearly significantp = 0.062
In the cohort with diabetes, a further interesting aspect is the nearly significant association between mortality IRR and the prevailing therapy with insulin at basal (1.50 (95% CI: 0.98–2.28); p = 0.062, which could be related to a prior worse metabolic control, a longer duration of diabetes, and/or to an intrinsic higher risk associated with treatment with this drug, as especially observed during the acute phase of the infection [31] , [32] , all hypotheses which, as a limitation of this study, it is not possible to evaluate.
