This approach is justified as long as the origin of the data is recorded with the data.
Our data set thus shows a significantly lower percentage of unsecured liabilities compared to other studies.16 This could be caused, as discussed earlier, by the origin of the data set.
The database provides means to identify the origin of the data, i.e., the specific inventory a compound originated from.
This was criticised by Channel 4's factcheck blog which questioned the origin of the data and stressed that the rate did not include students.
