Small HDL (s-HDL) Particle Concentration in Plasma at Baseline
Small high-density lipoprotein (s-HDL) particle concentration plasma measured by Ion Mobility Assay. For more information on the measurement used please refer to this article: https://doi.org/10.1002/alz.12649
Time frame: baseline
Population: Due to a non-optimal sample preparation procedure, a number of the samples allocated for the small HDL-C particle analysis were lost and therefore no samples were assessed for this measure.
