This is one paper on one hospital and only looking at data after the fact.
Across the USA if you were hospitalized more than 10 days you had a much higher chance of survival. It did not depend on any medication given. That is a stat that runs across the board. This study only includes patients that were given a treatment AFTER 10 days of hospitalization. Most of those that were going to die did so before this study would show they would of been treated.
