P O B Is an L D L Particle Metric

The particle number da a came once they sort of identified, i a way of assaying particle numbers. Opos identified an l d l particle concentration using these methal signals coming out of the methal groups that are on clustral ester and triglisrides and phospho lipids. And it clearly became evidence that p o b is a better rist factor. But if we do some imaging, we see placin than does the calustral measurement perself. So it's not a surragative particle. They are particle measurements, p o b or l d.
