And in composite scoring, the five lifestyles yielded a so-referred to as dose-reaction affiliation: in comparison with the cheapest-scoring quartile, ADRD danger was decreased 12{b574a629d83ad7698d9c0ca2d3a10ad895e8e51aa97c347fc42e9508f0e4325d} in the 3rd-highest-scoring quartile, 21{b574a629d83ad7698d9c0ca2d3a10ad895e8e51aa97c347fc42e9508f0e4325d} in the next-greatest-scoring quartile, 36{b574a629d83ad7698d9c0ca2d3a10ad895e8e51aa97c347fc42e9508f0e4325d} in the best-scoring quartile.
