Other related information According to the report of Fang et al, they suggested that there is a margin of blood pressure ( >5+/-10 mmHg ) between the group of amlodipine and nifedipine. This finding was more than expected at initiation of CARILLON study.

As a result of consideration to ethics and safety, CARILLON study should be aborted without prolonging registration period.
