The EMI Occurrences row represents the number of times EMI occurred during a test (n = 20). One experiment was defined as all testing performed on one medical device with one RFID system. Therefore the All Experiments column indicates whether any EMI occurred for a particular RFID system and does not indicate whether multiple effects were caused by the same RFID system. Production years for devices tested in parenthesis.
