>The mean (and standard deviation) age of 2016 decedents was 50.0 (±11.4) years and 52.3 (±16.8) years for the 2024 decedents.

27 organ material samples from 2016 and 24 samples from 2024 - but they don't say if they're from different people. I assume they are but it's not stated.

Just wondering how much the increased age would have contributed to differences between the two years.
