blindness
BLIND, BLINDNESS
The study was conducted as a randomized, double-blind, placebo-controlled trial at Divakar Hospital, Bangalore, India. The subjects (N = 30) were randomized, using a random number generator. An alphanumeric code was generated for both the investigational products to improve the blindness of the study and the concealment of allocations. Block randomization (only 1 block) was followed wherein the subjects were randomized to receive either of the 2 investigational products. The study supplements were coded and supplied to the study site, in a manner to maintain the blind throughout the study. The randomization codes were kept strictly confidential and were accessible only to authorized persons on an emergency basis as per the Sponsor's standard operating procedures until the time of unblinding.
