It’s very confusing to keep track of all the lists of things presented ‘respectively’, yes! Interesting though, seems that from a total cholesterol level of 200 to 229 mg/dL (or a bit lower optimal range for the youngest age groups), raising the level causes increased mortality, but below that level, raising it decreases mortality even more than raising from a high level increased it, so it seems like ‘cholesterol == bad’ is wrong, having really low levels (it seems) can be much worse than having high levels. The second bit seems to say that increases from the high range were worse (increased mortality rates more) for younger people and but the effect decreased pretty linearly as you go up through the age groups, but the positive effect of increasing from a low level was pretty consistent for each age group, except for the youngest and oldest group.
