"DESPITE THE HYPE, GILEAD’S REMDESIVIR WILL DO NOTHING TO END THE CORONAVIRUS PANDEMIC"

FTFA:
>While some patients and their families have spent the past few weeks frantically trying to procure remdesivir, another Covid-19 treatment has been quietly been shown to be more effective. Although neither option appears to be the much-needed cure for Covid-19, a three-drug regimen offered a greater reduction in the time it took patients to recover than remdesivir did. People who took the combination of interferon beta-1b, lopinavir-ritonavir, and ribavirin got better in seven days as opposed to 12 days for those who didn’t take it. Critically, the treatment has another leg up on Gilead’s: It clearly reduced the amount of the coronavirus in patients who took it, according to a study published in The Lancet on May 8.<
I suspect you have the wrong idea about how the results of the trial are supposed to be interpreted. The point isn't to compare to results outside the study. You should only compare the intervention group to the control group in the same study.
