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