Figure 3. Protocol and non-protocol mean CPD with outliers excluded. Note: five patients were removed from the protocol group due to outliers costs (CTPE) and four subjects in the non-protocol group did not have cost data available. Therefore, the sample sizes for this analysis were 10 for the protocol group and 11 for the non-protocol group.
