lipoprotein insulin resistance correlates with cardiovascular disease
In plain terms: Does an insulin-resistance lipoprotein score beat LDL for spotting early heart disease?
In the cited women's cohort the LPIR score was much more strongly tied to premature CHD than LDL-C, and independent cohorts confirm it tracks atherosclerosis — but it is associative, not proven to 'beat' LDL causally.

What the evidence shows
A lipoprotein-insulin-resistance (LPIR) score discriminated premature coronary heart disease better than LDL-C in a large women's cohort - real support for the 'metabolic context matters more than LDL alone' framing, though single-cohort and observational.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
