The following table should be used as a general guide when using and interpreting the data. You should directly consult with the provider of any data source for a detailed assessment of each source’s quality, accuracy and use.
Where we provide access to data either through reporting summaries or data download, we do not recommend treating all the sources as comparable when interpreting against any hypothesis or use case.
