Also age is huge so people shouldn't be reading much into a reading of 0 unless you're over 65. https://dirjournal.org/articles/coronary-artery-calcium-scor... (see table 2)

Imagine claiming "my diet is great, i got 0% on my calcium score" when that just means you have the same score as 95%+ of people at age 40.

By 55, 25% of people start showing some % of calcium and at 65, 75% of people have a reading on calcium score.

So anyone under 45 being proud of a zero score is just silly.
