Cheaper if the total cost of the 5 OS's is ignorable. More problems: loss of perceived equipoise limiting RCT recruitment, too much influence of OS results on clinical practice before the too-late RCT is launched, RCT not launched because of impressive OS, etc.

Recently I heard someone say “we ran an RCT based on our associational studies and unfortunately found null results.”
How did we get in a place where we don't see the problem in using associational evidence (which cannot even say the word cause) to inform RCTs.

If you're not, listen to this.
Get a guitar or some drums, or a trumpet. Pick up a brush, a pencil, some clay or a welder.
Just make shit. It doesn't have to be good (eventually it will be) just make music, art or write or whatever.
It's literally never been more important.

Python people, please embrace missing values. I want the output with all the observations, not only the filtered ones without missing values. If I need filtering, I will do it myself.
