INS and COVID-19: When COVID‐19 and non‐COVID‐19 viral pneumonitis patients were matched (1:1, N = 36 per group) by the level of respiratory support required and pre‐existing diabetes status, the proportion of patients requiring insulin (COVID‐19: 41%, non‐COVID‐19: 49%) and insulin dose was similar in those who were treated with insulin (Figure 1C,D and Appendix S1: Figure S2C,D).
