From: The prognostic role of plasma fibrinogen in adult secondary hemophagocytic lymphohistiocytosis
Cubic spline plot of the association between plasma fibrinogen and the risk of mortality among adult onset HLH patients. The solid line and dashed line represent the estimated hazard ratios and their corresponding 95% CIs, respectively. Analyses were adjusted for age, PLT (platelet), EBV, ferritin, malignancy—associated HLH (MHLH) and treatment strategies
