Figure 3 Kaplan-Meier curves displaying the estimated infection probability for different groups of patients. Time-dependent risk of infection was assessed using the log-rank test. Infection probability was calculated as one minus cumulative survival probability. (C) Shows infection probability for 3 groups. Patients with 0 or 1 or 2 risk-factors. (A) Shows infection probability for 2 groups. Patients with expander or with prosthesis. The cumulative infection probability was higher for the use of an expander compared with a prosthesis (P=0.031). (B) Shows infection probability for 3 groups. Patients with PCR negative for MSSA/MRSA, with PCR positive for MSSA/MRSA who did and who did not perioperatively receive mupirocin. (D) Shows infection probability for 2 groups. Patients either did or did not receive treatment with CHTH. The cumulative infection probability was higher for treatment with CHTH than without CHTH treatment. However, the differences were not statistically significant (P>0.05). PCR – polymerase chain reaction; MSSA – methicillin-susceptible S. aureus; MRSA – methicillin-resistant S. aureus; CHTH – chemotherapy (adjuvant or neoadjuvant). These figures were created using IBM SPSS Statistics (version 29, IBM Corp, Armonk, NY, USA).
