Association between stages of AA. Comparison of serum fibrinogen (mg/dl) in patients with appendicitis group 1 (stage I ro III, n = 68) and group 2 (stage IV, n = 47). Quantitative variables were expressed as msdians (ranges). Analysis of the fibrinogen levels between the groups was obtained by analysis of variance with Mann–Whitney (p < 0.001).

ROC curve and area under the curve (AUC) of fibrinogen in stage IV. The graphic illustrate the distribution of values to distinguish UA group (stage I to III, n = 68) and CA group (stage IV, n = 47) using the fibrinogen values. The AUC for the whole procedure was (95%Cl 0894–0985).
