RE: Diabetes, Fasting Glucose Analysis, And How Likely Am I To Die Anyway?
Your point for the error in the second figure is good to keep in consideration. How confident can we really be that there is a statistically relevant difference between those two age groupings. There is clearly a huge variance in the data for the younger group.
That gets at another point, confidence in conclusions we could try to draw from the data. It's defined by the quality of the data.
However my question was more in identifying why younger people might have a higher hazard ratio then older people. The answer I am thinking of is very certainly not the only one, nor the only thing worth considering from the data. I was curious what people might come up with.
Let's see. Ignoring the error, I would tend to say this may be connected to the first figure and the genuine differences between the two age categories (that are not really visible on the third figure). But I may be wrong here :)
