Very interesting.
Linked below is a graphical representation of the "Top 20 clinical trial participant countries worldwide in 2015-2019, by share of participants."
The U.S. is by far the big leader with 35% of the participants, with the bulk of the remaining testing being done in European countries, and the rest scattered in a few other countries throughout the world.
Ukraine does indeed come in at 2%, but it's REALLY interesting to see that Russia comes in at 4% (!)
It's very curious indeed to wonder what the impact of the war has been on the trials that were being conducted in those two countries. Likely not a good one.
I was also a bit surprised to see Canada coming in at only 3%, and the U.K. at 2%. I would have thought those two might have had larger numbers.
