Figure 1 Simplified schematic representing the decision between prophylactic mesh vs no mesh placement at the index operation. (A) Patients entering the model undergo abdominoperineal resection for rectal cancer. (B) If they survive, they enter into the cohort Markov model. APR, abdominoperineal resection; OR, operating room; PSH, parastomal hernia.
