Putting this up for argument rather than for agreement. I have read it twice and I am still not certain what it supports.
ApoB is the more informative number and it is cheap. LDL-C estimates cholesterol mass in atherogenic particles; ApoB counts the particles, and it is particle count that tracks risk — which is why the two can disagree and why the disagreement is the clinically interesting case. Triglycerides fall substantially with weight loss and improved insulin sensitivity, HDL moves modestly, and LDL-C often barely moves at all, which surprises people who expected everything to improve together.
Where I think it is weakest: the population was selected and supported in ways a real cohort is not, so I would read the effect size as a ceiling rather than an expectation.
The question I want answered is whether an unchanged LDL-C alongside a large triglyceride fall is a good result or a bad one, because ApoB and LDL-C seem to be telling different stories. I have searched first, so if this is covered somewhere point me at it and I will read it.
Note on sourcing:
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.
