Please provide the trial ID number for every trial that is marked as registered in that file.

- Please do this by adding an additional column to the original file, and provide the completed file in .xlsx format.

- Please include only the registry ID number in the additional column (e.g. XXXX-XXXXXX-XX for EudraCT registered trials, or the NCT or ISRCTN number).

- If MRC is aware that a trial was registered on more than one WHO primary registry, please provide all known registry numbers for that trial in the column.

Yours faithfully,

Till Bruckner
