Pie diagram of each group and the pre- (a) and post-measurement stages (b) for ethics (left) and CRM groups (right). The shaded parts represent the scenarios in which an error was corrected. The white area represents scenarios where neither the compression rate nor the compression depth was corrected. a Ethics: compression rate corrected 7.7% (n of corrections (oc) = 2), total: 7.7% (noc = 2), n = 26; CRM: compression depth corrected in 3.2% (noc = 1), both mistakes corrected in 6.5% (noc = 2), total: 9.7% (noc = 3), n = 31. b Ethics: compression rate corrected in 7.7% (noc = 2), total: 7.7% (noc = 2), n = 26; CRM: compression depth corrected in 12.9% (noc = 4), compression rate corrected in 9.7% (noc = 3), both mistakes corrected in 12.9% (noc = 4), total 35.5% (noc = 11), n = 31
