The decision on the allocation of a given study site to the categories of "urban", "rural" or "semi-rural" was based upon the relative population density and level of infrastructural development of the communities surrounding each site.
Upon receipt, data will be entered onto a specifically designed password protected database by designated research staff, all individual data will be de-identified through allocation of a unique study code.
The randomized trial [ 13] supporting the hypothesis did not use concealment of allocation, a study quality indicator for randomized studies that is important to avoid bias during the randomization process [ 48].
Iain Chalmers, a founder of both the Campbell Collaboration and its older and better established medical sibling, the Cochrane Collaboration, identifies an apparent example of random allocation in a study carried out in 1927 of how to persuade people to turn out to vote in elections.
Once a patient has been randomised they will be given the next available study number which will equate to an allocation of study drug dispensed in two bottles (labelled Bottle A and Bottle B).
Actually, the most interesting piece of policy development in the stimulus bill is not an expensive budget allocation, but rather the commissioning of a study - a serious effort to explore in depth how to create a greener national electric grid, one that would usher in the fourth great era of human energy development consumption.

The study designs of intervention studies included comparative before and after studies[ 16- 21], randomized trials[ 11, 22] a comparative study (with a non-random allocation of study units)[ 23, 24], and cluster randomized trials[ 25, 26].
The allocation of the study participants to intervention or control group was done using a random generator, equally distributing the study participants.
Study nurses and participants were not blinded to the allocation of the study clinic at the time of screening.
