President Trump received mostly the same treatment as anyone would get for COVID-19, except for one experimental drug and the speed of his care.

The list of drugs shown effective for treating COVID-19 got longer Tuesday, even as another well-used drug lost some of its luster.

The study, published in JAMA Internal Medicine, showed just over 27% of ICU patients treated with tocilizumab died within a month, compared with 37% of those just as seriously ill but did not receive the drug. .

"If you wait too long, you're waiting for irreversible organ injury to have occurred," he said, and the drug may no longer be effective.

About 20% of the ICU patients examined had symptoms for just a few days before landing in intensive care, he said.

In an unrelated result, the World Health Organization found four other drug regimens given to hospitalized COVID-19 patients did not reduce deaths, hospital stays, or the likelihood of requiring ventilation. 

"We will continue to use remdesivir in our patients hospitalized with COVID-19," he said
