In AMI2, the check for clinical trial states:
OR:
AND NOT: "Occurrence A of Patient Characteristic: Clinical Trial Participant" ends before start of "Occurrence A of Encounter, Performed: Hospital Measures-Encounter Inpatient"
AND: "Occurrence A of Patient Characteristic: Clinical Trial Participant" starts before or during "Occurrence A of Encounter, Performed: Hospital Measures-Encounter Inpatient"

In AMI7a, 8a, and 10, this same logic states:
OR:
AND NOT: "Occurrence A of Patient Characteristic Clinical Trial Participant: Clinical Trial Participant" ends before start of "Occurrence A of Encounter, Performed: Encounter Inpatient"
AND: "Occurrence A of Patient Characteristic Clinical Trial Participant: Clinical Trial Participant" starts before or during "Occurrence A of Encounter, Performed: Encounter Inpatient"

Note that in AMI7a, 8a, and 10 it states "Patient Characteristic Clinical Trial Participant: Clinical Trial Participant" Where in AMI2 it states: "Patient Characteristic: Clinical Trial Participant"
