They missed one.<p><a href="https://pubmed.ncbi.nlm.nih.gov/31796677/" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/31796677/</a><p>> Therefore, we conducted a proof-of-concept study that randomized 70 amnestic MCI patients to a 1-year program of AET or a non-aerobic stretching and toning (SAT), active control group. Thirty-six patients completed both baseline and follow-up MRI scans, and cerebral WM integrity was measured by WM lesion volume and diffusion characteristics using fluid-attenuated-inversion-recovery and diffusion tensor imaging respectively.<p>WM lesions/integrity aren't the same thing as amyloid levels, though it looks like a bunch of studies have looked at them together and have found relationships. I'm sure they appear together in the same text a lot.<p>I think that might be one conflation. It also got the journal wrong, and I don't see Cooper Inst. referenced in the affiliations section (though I'm not sure what form that would take).<p>But I'm pretty sure that's the 70 person study being referenced, unless it was another that was run just like it. Worth noting also that 36/70 (the final group size) is just shy of 52%. I think that might be why it was "52 weeks" and not "one year" for the program.<p>I believe that's medicalspeak for the 6th and 7th bullet points in the Bing summary. I'm not sure if the full article would reflect the rest.<p><a href="https://pubmed.ncbi.nlm.nih.gov/?term=%22Texas%20Southwestern%22%5BAffiliation%5D%20aerobics&filter=years.2020-2020&page=11" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/?term=%22Texas%20Southwester...</a><p>For me, it's result #114.
