β: coefficient provided by the Cox's regression model for a particular patient and cytokine; HR: hazard ratio (represents the factor by which the hazard changes for each one-unit increase of the cytokine expression); 95% CI: upper and lower limits of the confidence interval with a significance level of 0.05.
