What is a co intervention?
Co-interventions are additional treatments, advice or other interventions that a patient may receive, and which may affect the outcome of interest.
What is co intervention bias in research?
Patients often receive multiple treatments, in addition to the intervention being studied, which could impact the outcome of interest. Co-intervention bias occurs when different groups receive different co-interventions.
What is intervention bias?
Intervention biases are a broad category of biases that result from systematic differences in the way in which the intervention was carried out between groups, or differences in how subjects were exposed to variable of interest. Also known as exposure bias.
What is contamination in research?
Contamination occurs when an inter- vention administered to an intervention group of an experimental study filters into the control group.
What is co intervention RCT?
(kō-in-tĕr-ven’shun), Application of additional diagnostic and/or therapeutic procedures to members of either the study group or control group in a randomized controlled trial.

What is the difference between allocation concealment and blinding?
The key difference is that allocation concealment is done before/along with randomisation, while blinding is usually happened after randomisation.
Is blinding always possible?
Blinding is certainly not always easy or possible. In trials of different styles of patient management, surgical procedures, or alternative therapies, full blinding is often impossible. In a double blind trial it is implicit that the assessment of patient outcome is done in ignorance of the treatment received.
What is classification bias?
Classification bias, also called measurement or information bias, results from improper, inadequate, or ambiguous recording of individual factors—either exposure or outcome variables. Classification bias also can occur if different methods of diagnosis are used for the patients.
What is blinding in a research study?
Blinding, in research, refers to a practice where study participants are prevented from knowing certain information that may somehow influence them—thereby tainting the results. This blinding can include clinicians, data collectors, outcome assessors and data analysts.
What is compliance bias?
We define compliance bias as the introduction of systematic predilection into collected self-reports as the result of differences in response rate between participants.
What is contamination in RCT?
Treatment contamination is defined as the receipt of active intervention amongst participants in the control arm of a randomised controlled trial (RCT) [1]. The effect of contamination is to make the control arm more similar to the active intervention arm, i.e. to dilute the treatment contrast.
Is there a known time period for co-intervention?
There was no known co-intervention, and the time-period of 2 weeks between the assessments was too short for the acquisition of further experience to explain the improvement. Death certificates: let’s get it right!
What do you mean by co-intervention bias?
Co-intervention bias. Knowledge of which treatments have been received by which study participants can affect adherence to assigned treatments and result in the biased use of other treatments (co-interventions). These biases can be reduced by using placebos to conceal the identities of the treatments being compared.
Who is Intervention Inc and what do they do?

Why are contact lenses not included in co-intervention studies?
One study was not included because it used contact lenses as a co-intervention. Topical ophthalmic NSAIDs reduce pain faster than placebo. (Patient Oriented Evidence That Matters: practice recommendations from key studies)
