What does "randomization" mean in the context of a clinical trial?

There are many clinical trials that use the randomization technique in order to select what kind of treatment should be administered to the patient reagarding the research methodology ( in comparison to a placebo or another treatment).

Randomization is performed by a computer, not a medical professional, because this way it is easier to ensure equal opportunities for all participants to access the treatment and avoid any kind of bias.

Using this technique helps to confirm that any outcome from he trial is completely objective and that it not a reflection of the particularities of the participants.
