rob-domain_description	Randomization requires that each human subject or animal had an equal chance of being assigned to any study group including controls (e.g., use of random number table or computer generated randomization).	Allocation concealment requires that research personnel do not know which administered dose or exposure level is assigned at the start of a study. Human studies also require that allocation be concealed from human subjects prior to entering the  study. Note: a question under performance bias addresses blinding of personnel and human subjects to treatment during the study;a question under detection bias addresses blinding of outcome assessors.

@rabstejnek another example of switching from nested JSON to SQL

@shapiromatron looks like we need to rewrite the test data files after merging in main

I'll push an updated commit.

Everything looks good!
