The purpose of this white paper is to compare the ERs in the MDD and AIMDD to the SPRs in Annex I of the new MDR. Where there are 13 ERs in the MDD and 16 in the AIMDD, there are 23 SPRs in the new MDR. The overall text and requirements are expanded, but the scope and topics are consistent overall with the previous directives with a few notable exceptions.
