Short summary is there are a few SMART stats that seem to predict failure way more than others, which is probably obvious. But we aren't PhDs in statistics and it isn't our area of focus, so....
I can't comment on their findings, but it's DEFINITELY an interesting thing to study now that we have almost 10 years of these drive stats across a pretty big drive farm.
We looked into it a little, some notes written up here: https://www.backblaze.com/blog/what-smart-stats-indicate-har...

These 5 guys wrote another paper based on the Backblaze SMART data to train up a Bayesian network to predict failures: https://ieeexplore.ieee.org/document/8489097
