Masking Details

An independent statistician generated a blocked randomization sequence using computer-generated random numbers; participants received either zonisamide and acetaminophen or propranolol and acetaminophen from a specially trained and qualified nurse. We prepared Sequentially numbered opaque sealed envelopes and 600 labels for each drug labeled Drug A or B. According to the randomization chart, put them into envelopes numbered 1 to 600. Envelopes were attached to the patient's files. Patients were recruited sequentially and were given enrollment numbers starting from 1, which were mentioned in their files. Files with the same number as the patient enrolment number were opened and the patients were assigned to receive drugs A or B. Drug A included zonisamide and acetaminophen, and Drug B included propranolol and acetaminophen. The statistical analysis was performed by an independent statistician who did not know the treatment protocol of groups A or B.
