The data set includes all data of the questionnaire – it is called 'month18’.
     In the last update some missing-codings (.M) of question 45,47, 68-47
     were revised.  All other data were not changed in the data set.

     

     All tables are provided as SAS- and SPSS-files.
                                                         

       An annotated CRF is also included (variable names were added in red and coding in  blue
       colour onto the original questionnaire).
