External validation of the LPS against an independent geographically diverse population yields high NPV. This may support non-specialist colleagues who may have concerns about mis-diagnosing a PTA. The COVID-19 modification of the LPS has a similar NPV, which may be of use where routine oral examination is to be avoided during the COVID-19 pandemic.
