... and yet, they are surprising near uniform in the triad thus far. I’m excited to see upcoming centenarians and how much/little we see this phenomenon continue.

I want to see how common the triad is in centenarians (High LDL, high HDL, low TG) when tested a decade and a half earlier.

But you'd still be seeing survivorship bias there. You're seeing the people who, for whatever reason, can be in that state and live for a long time. Doesn't say much about the rest of the population imo

Survivorship bias makes sense if we were testing these 100/101 year olds a year earlier. But I'm emphasizing these markers (high LDL, high HDL, low TG) were taken 15 years earlier when they were age 84/85. The other 118 of those 84/85 taken at that time are not centenarians.

Well, the sample size is still tiny. But even so, the case-control you're suggesting would definitely be open to survivorship bias, because you're selecting people who have lived a very long time. More appropriate to start at, say 50, and see how many make it to 100

You could do this with a retrospective cohort design rather than the case-control you're thinking of. This tells you how many people have the triad and die vs the number that survive to 100

Would love to. If you've followed me for a while, I know just how much I'd love to get ahold of more raw datasets to test this out directly. Obviously, Framingham Offspring would be especially useful given followups, etc.

Yeh we should all move to Scandinavia it's the mecca of long-term linked data. Would be amazing to work with the datasets they have in Sweden and Denmark

Believe me, I could have a very un-twitter-like rant about access to data in this industry. Coming from technology, we are awash in free, robust data — not so in nutrition/medicine. The irony is that the latter would benefit far more in impacting our lives if it were open source.

That we can definitely agree on, but I also understand it. As a society, we are far too free with our non-medical data, even if it's incredibly private. Conversely, we're incredibly cagey about anything medical, even if it's entirely deidentified and boring
