Concentrations of other lipids such as HDL-C9 and the presence of other variants in genes such as PCSK9 that affect LDL-C but were not identified in genome-wide association studies could be important because they may affect the outcomes of sepsis.23 Seventh, we studied white patients admitted to a tertiary-level US hospital with infection who had LDL-C levels measured at least 1 year before admission or had undergone genotyping, which limits the generalizability of the findings. Here, C9 is linked to infection.
