Randomization was achieved using a computer-based random number sequence.
Patients were randomised in a 1 1 ratio using a computer generated random number sequence and study allocations were placed in pre-numbered, sealed envelopes.
After their consent was obtained, patients were randomly assigned in two groups, using a random number sequence, generated with a proprietary computer application, according to a randomized block design.
For adequate sequence generation, two studies used randomized block designs [ 6, 8], one study used a computer-generated random number sequence to allocate patients to the treatment and control groups [ 16].
(That last technique worked well until one night a janitor switched off the lamp, and the supposedly random number sequence became a string of straight 0s).
A random number table was used to generate the random number sequence.
In each case, the random number sequence that is generated is identical to that produced on a CPU by the standard sequential algorithm.
At the second visit, at the end of this baseline period, the patients still fulfilling the inclusion criteria were randomly assigned (using a computer-generated random number sequence), in equal numbers, to three different treatment groups [24].
An administrator independent from the study generated the random number sequence in Excel using RAND function.
Animals were randomly assigned to either control or lesion groups using a random number sequence (lesion N = 8; control N = 7).
Results for all simulated epidemics were determined from the average of 40 individual simulation runs, each with stochastic choices made using a different random number sequence.
