The associations between the primary outcomes and PUFA levels. The cumulative incidences of the primary endpoint (all-cause death) were estimated by using the Kaplan–Meier method. The patients were divided into two groups, based on the median levels of (A) EPA, (B) DHA, (C) AA, (D) DGLA, (E) EPA/AA, (F) DHA/AA, and (G) AA + DGLA/EPA + DHA. Log-rank testing was performed to study the influence of PUFA levels on primary endpoint. EPA, eicosapentaenoic acid; DHA, docosahexaenoic acid; DGLA, dihomo-gamma-linolenic acid; AA, arachidonic acid; EPA/AA, ratio of EPA to AA; DHA/AA, ratio of DHA to AA; AA + DGLA/EPA + DHA; ratio of AA + DGLA to EPA + DHA.
