What the research says about 14 ways to age better

Each row is something people do for a longer, healthier life, from exercise to GLP-1 drugs. Each column is a health outcome. A dot counts the papers in our library on that pairing. Its fill shows the strongest grade among them.

41 of 98 pairings have papers in our library. 57 are still empty.

How to read the dots

Size: how many papers: 1; 2–3; 4–7; 8+
Fill: strongest grade of any one paper: Strong; Moderate; Preliminary
Size: how many papers: Empty: no papers in our library yet. Research may still exist.

How this map is computed

A mark's size is the number of papers we hold on that pairing. It is a count, not a weighting by study design or sample size.

The fill shows the strongest grade in the cell. One Strong paper among four Preliminary ones still fills it dark, so open the cell to see the rest.

Grades and verdicts are assigned by a named person, never by counting.

An empty cell means our library holds no paper on that pairing yet. It is a gap in our library, not proof that nobody has studied it.
