The only reason that p value is a bit high in that second multivariate analysis is because of the uncertainty of how much all the different risk factors like hypertension, T2DM, age >= 60 etc. affect ICU admission numbers.

But even with those variables controlled, the 95% confidence interval is 0.003-0.25, which at worst is a 4-fold reduction in ICU risk.

We should also note that the Calcifediol treatment group had 14 patients ≥ 60 years old, and the non-Calcifediol group had 5. So the study looks even better with that in mind...
