What it invalidates is the notion that research that does not include RCT is automatically wrong. We currently see this in action in the way corona is being treated. When we were told that masks don't help stop the spread of corona, what was really meant was "there has been no RCT that demonstrates that the spread of corona is less in a mask-wearing group" - in other words, the issue was simply untested, but this was formulated in such a way that a lay person would believe it was already known that masks have no effect, which is something completely different. The use of Ivermectin is arguably in the same situation right now.
