Hi, I went through datashield example on the OBIBA Demo server [1]. I saw that executing this code …

> D ← opal.execute(o,‘CNSIM1’) head(D)

… returns individual patient data:

> PM\_BMI\_CONTINUOUS GENDER 1 33.67 0 1003 25.86 0 1008 34.77 0 1012 19.97 1 1010 36.09 1 1031 27.84 0

I am confused. Wasn’t DataShield about not disclosing individual patient data?

Could you explain why this is happening?

Hi,

This is not Datashield. That is pure R usage to access opal and it is highly recommended to only grant administrators the right to perform such operations. Datashield uses different web services access points with extra checks.

See [Using DataSHIELD - Opal documentation](https://opaldoc.obiba.org/en/latest/r-user-guide/datashield.html).
