The first reported clinical trial was conducted by James Lind in to identify treatment for scurvy. Fisher's experimental research and his writings popularized randomized experiments.

Ethics[ edit ] Although the principle of clinical equipoise "genuine uncertainty within the expert medical community For one, it has been argued that equipoise itself is insufficient to justify RCTs. Trial registration[ edit ] Inthe International Committee of Medical Journal Editors ICMJE announced that all trials starting enrolment after July 1, must be registered prior to consideration for publication in one of the 12 member journals of the committee.

From most to least common in the healthcare literature, the major categories of RCT study designs are: Crossover — over time, each participant receives or does not receive an intervention in a random sequence.

Factorial — each participant is randomly assigned to a group that receives a particular combination of interventions or non-interventions e. Pragmatic clinical trial RCTs can be classified as "explanatory" or "pragmatic.

First is choosing a randomization procedure to generate an unpredictable sequence of allocations; this may be a simple random assignment of patients to any of the groups at equal probabilities, may be "restricted", or may be "adaptive. Non-random "systematic" methods of group assignment, such as alternating subjects between one group and the other, can cause "limitless contamination possibilities" and can cause a breach of allocation concealment.

An ideal randomization procedure would achieve the following goals: Generally, equal group sizes maximize statistical power, however, unequal groups sizes maybe more powerful for some analyses e.

This may occur if investigators can consciously or unconsciously preferentially enroll patients between treatment arms. A good randomization procedure will be unpredictable so that investigators cannot guess the next subject's group assignment based on prior treatment assignments.

The risk of selection bias is highest when previous treatment assignments are known as in unblinded studies or can be guessed perhaps if a drug has distinctive side effects.

Minimize allocation bias or confounding. This may occur when covariates that affect the outcome are not equally distributed between treatment groups, and the treatment effect is confounded with the effect of the covariates i.

If the randomization procedure causes an imbalance in covariates related to the outcome across groups, estimates of effect may be biased if not adjusted for the covariates which may be unmeasured and therefore impossible to adjust for. However, no single randomization procedure meets those goals in every circumstance, so researchers must select a procedure for a given study based on its advantages and disadvantages.

Simple[ edit ] This is a commonly used and intuitive procedure, similar to "repeated fair coin-tossing.

However, its main drawback is the possibility of imbalanced group sizes in small RCTs. It is therefore recommended only for RCTs with over subjects.

Permuted-block randomization or blocked randomization: This type of randomization can be combined with "stratified randomization", for example by center in a multicenter trialto "ensure good balance of participant characteristics in each group.

In these relatively uncommon methods, the probability of being assigned to a group decreases if the group is overrepresented and increases if the group is underrepresented.Whether you are looking for a clinical trial to take part in, information about how trials are planned or for trial results you can find it here.
