Causation is unimportant if it doesn't fit the narative.
It's disquieting, though, to see the Braille writing on the drive up ATM's.
No one reviews anything anymore, takes too much time and they're all in a race to come up with damning statistics first
This is a peer reviewed article--Journal of American Medical Association Internal Medicine is one of the biggies--the Marketwatch website is summarizing the original article which is behind a paywall. I read the original posted on the JAMA website

One concern that I have is the dataset itself does not seem to reflect all CA handgun sales accurately as the study seems to have adopted the lowest point of California handgun sales and picked a certain demographic. They also do not adequately account for why older firearm purchasers are excluded as substance abuse with alcohol can often worsen with age. This makes me suspect the Texas Sharpshooter fallacy. The fact that the law changed in 2000 which is not adequately accounted for in the data ignores a surge in purchases before the law changed.
"Lytton said concern over increased regulation likely contributed to the jump in handgun sales right before a
2000 state law limiting the number of handgun purchases to one per month took effect. Between 1998 and 1999, when the law was passed, handgun sales increased nearly 30 percent."

The surge in this buying before the study data begins could actually skew the data as I would suspect that those most attuned to obeying laws were buying prior to the change in the law.
There is also a consolidation of race into white/nonwhite that is not adequately explained.
If I find the time, I might do a more detailed critique as they rely on a research method that I am quite familiar with and which I have a suspicion that it might be inappropriate with the dataset used.
Peer review, while better than nothing, does not generally try to reproduce the results--thus we have the problem of replication of studies. This is a systemic problem where it is hitting all of the sciences and social sciences
https://infogalactic.com/info/Replication_crisis and it has also affected medical research. Even the hard sciences are having issues with most subfields demonstrating over one half of the studies published could not be replicated and even the same scientists are having issues replicating their own studies.
