I get the feeling that "ratios" are kind of an embarassment now - none of the recent expert statements I've read have anything to say about them, and they generally all repeat findings that raising HDL doesn't do you any good - so making your "ratio" better by increasing your HDL while keeping everything else the same isn't going to reduce any risks.A cholesterol of ten and HDL of two will give a "good" ratio of 5.
That NHS England lipid guidelines now only speak of non-HDL targets, and not ratios, is telling; but it doesn't fit comfortably with eg QRISK3 still being driven by the total chol / HDL ratio.
On the other hand, the HDL ratios stuff seems particularly odd given the large number of high quality studies showing U-shaped relationships between CV risk and HDL levels. Having a lot of HDL beyond a threshhold is associated with increased risk, as is well understood. So how that's supposed to fit with "ratios" - who knows?
Eg - this huge study just published: https://academic.oup.com/eurjpc/advance-article/doi/10.1093/eurjpc/zwab230/6491266?login=true
Both low and high levels of HDL-C were associated with increased mortality from CVD in the general population .... High HDL-C levels are not necessarily a sign of good cardiovascular health, especially in younger adults.
