An immune-related genes (IRGs) prognostic signature was constructed in sepsis patients. a 20 IRGs were screened by the LASSO regression model; b LASSO Cox regression analysis was used to compute the coefficients of IRGs; c forest plots illustrating the findings of a univariate Cox regression analysis examining the relationship between the 20 IRGs and 28-day survival in patients with sepsis; d the interactions of candidate IRGs are depicted in the protein–protein interaction network; e the correlation network of candidate IRGs; f forest plots illustrating the findings of a multivariable Cox regression analysis examining the relationship between the 20 IRGs and 28-day survival in patients with sepsis. LASSO Least absolute shrinkage and selection operator, AIC Akaike information criterion. ^*P < 0.05, ^†P < 0.01, ^‡P < 0.001
