Australian Paediatric Multi-Instrument Comparison (P-MIC) Study: Technical Methods Paper

The purpose of this document is to outline the methods used to conduct the Australian Paediatric Multi Instrument Comparison (P-MIC) Study. A study protocol for the P-MIC has previously been published, providing an overview of the planned P-MIC methodology. This document provides a detailed description of the methodology used to conduct the P-MIC study, providing additional detail to that which is publishable via peer reviewed journals, both to be fully transparent about study design, and to help others who may be interested in undertaking similar studies in future. The data cut for this version of the technical methods paper, data cut 3, was taken on the 27th June 2023 and includes 7,226 children and their caregivers (see Table 1). This data cut represents 100% of the total planned P-MIC participants.
