Fig. 1From: Comparative evaluation of sump drainage by trocar puncture, percutaneous catheter drainage versus operative drainage in the treatment of Intra-abdominal abscesses: a retrospective controlled studyCumulative incidence of subsequent surgery among the patients in Trocar, PCD and SD groups (A). Patients in Trocar group tended to have a lower incidence of subsequent surgery during follow-up period (p = 0.070). Cumulative incidence of ultimate stoma creation among the patients in Trocar, PCD and SD groups (B). The cumulative incidence of ultimate stoma creation of the patients receiving trocar puncture was significantly different among three groups during follow-up period (p = 0.011). Cumulative incidence is one minus the estimate of the survival functionBack to article page
