Honest question: How would you determine if something is "obvious" from the statistics? I can't find anything that goes into that level of detail, or addresses it at all. So, the question becomes, is it even /potentially/ a big enough issue to be a factor?
I think it is personally reasonable to come up with a hypothesis (note: just a hypothesis at this point!) of if a large percentage of people are pushing off preventative care, then it seems likely a large number of those people will likely not have issues that will become terminal, treated in time to save their life.
So let's look into it a bit further:
41% of all adults didn't goto the ER or preventative care (see: https://www.cdc.gov/mmwr/volumes/69/wr/mm6936a4.htm )
For just mammograms which is a small number of overall terminal issues that could be found by preventative screenings (and obviously don't make up the whole number by itself) :
Preventative care "all but stopped" for mammograms during the start of the pandemic in 2020 (28k / month in 2019 people had them see: https://www.breastcancer.org/research-news/mammogram-rates-rebounding-after-pandemic)
If you have a mammogram there is a 0.5% chance you will get called back indicating you have cancer (see: https://www.urmc.rochester.edu/news/publications/health-matters/mammograms-facts-on-false-positives)
Similar issues look like they exist for other types of cancer (prostate, etc.), I didn't want to spend the hours to put links supporting those other issues in this post, but, I did look at a few and the numbers are easily available via google.
Again, this is just for breast cancer, which doesn't include any numbers from other preventative screenings (pap smear, prostate, lung cancer, heart issues, etc.), and breast cancer isn't even near the largest - it was just easier to get data for this post. Further, the CDC link specifically indicated a percentage of those people put off going to the ER as well, which seems even worse.
At a minimum based on the above, the deaths are being skewed by it - that much is obvious. Can you find any studies or articles indicating that lack of preventative care couldn't be responsible for the excess death numbers, that goes into any type of detail and has sources - or just for curiosity's sake, any studies that even imply they control for that and how? I can't, so I'm genuinely curious if they are available..
Covid is a horrible disease that has cost millions of lives. Many people aren't getting vaccines (or taking basic measures to prevent the spread) for various reasons which is costing even more lives every day. But, when the information being provided to the public is inaccurate (e.g. misinformation) it causes much more harm than good.
The truth and approaching things in an analytical and scientific way is important. People are treating this more like some weird type of religious / political war, and it's costing lives.
