I think this is a overly pessimistic take. It would be nice to see a longer term study. And no people shouldn't be buying this in IndiaMart but critical analysis of studies isn't just about being as pessimistic as possible. It's overly pessimistic as it's not constructive. Instead of asking for longer term studies you declare the effect probably won't last. There are loads of criticisms one could make of the study and wider hypothesis. But as with all criticism it should be constructive where reasonable.
