What to check first
- Define the purpose and lawful access to data
- Check missingness, coding and representativeness
- Have qualified domain experts review interpretation
Define the dataset before interpreting it
Clarify the population, units, coding system and purpose of collection. Missing records, changes in definitions and selection bias can affect what the dataset represents. Access must be appropriate to the data and applicable requirements.
Use qualified domain review when conclusions could affect care or policy. Protect identifying information and avoid uploading sensitive records to unapproved tools. This article discusses analysis planning, not clinical diagnosis or treatment, and includes no fabricated benchmark statistics.
