Erratum

Following the publication of this article [1] it was brought to our attention that there was an error in the ‘Total cost’ paragraph of the ‘Results’ section.

The paragraph currently reads: “The total cost of OPV, EDV, IA, and prescribed medications in the CPP-R cohort was 1.46% lower, as compared to the PCP-A cohort (p = 0.026) (Data not shown due to proprietary nature of data).”

This should instead read: “The total cost of OPV, EDV, IA, and prescribed medications in the CPP-R cohort was 119.6% lower, as compared to the PCP-A cohort (p = 0.026) (Data not shown due to proprietary nature of data).”
