Our findings indicate that vitamin D supplementation has a protective effect against the incidence of COVID-19 in RCT studies (OR 0.403, 95% IC 0.218, 0.747)

That's a reduction in risk of 59.7%

in the incidence of COVID-19 in analytical studies (OR = 0.592, 95% IC 0.476–0.736)

That's a reduction in risk of 40.8%

and in ICU admission (OR 0.317, 95% IC 0.147–0.680)

That's a reduction in risk of 68.3%

I mean, vitamin D is essential to the working of the immune system, and most people with indoor jobs are insufficient, so you would expect there to be a benefit when fighting off infections to vitamin D supplementation, and these figures are significant.

The 80% is from the section not summarised in the abstract looking at healthcare workers only. One of the five studies comes up with a 97% reduction in risk, that brings that group up to about 80%.

That one paper didn't look at COVID-19 specifically. It looked at all influenza-like illnesses. Possibly COVID-19 remains more dangerous in even with sufficient Vitamin D than other influenza-like infections.
