1.In a study which found that diabetes was one of the few conditions that was independently associated with mortality inCOVID patients, the authors argued as follows:

2.Diabetes is a causative factor of hypertension and metabolic syndrome and these, in turn, can cause heart, vascular, liver, neurological and kidney diseases. Our study therefore suggests that diabetes might be a triggering factor for these disorders and therefore is related to mortality in patients infected with SARS-CoV-2. Type 2 diabetes mellitus has also been reported to be one of the most important factors related with COVID-19 severity in four previous investigations conducted in China, Israel and Italy.Furthermore, diabetes is linked to a higher mortality in other viral infections, such as those caused by influenza A(H1N1), MERS-CoV and SARS-CoV viruses [REFS].

3.Which one or more causal criteria are supported by these statements?

4..Plausibility/Coherence

5..Dose-response

6..Temporality

7..Consistency

9..Experiment

10.Strength of the association

I chose the last 3 but not sure.
