For example, differences can occur with the incidence rate or odds ratio and thus is not reflective of the true difference between the groups studied and the target population.The likelihood of selection bias, recall bias, and other biases are so high in certain clinical situations that no observational study could address the question with an acceptable risk of bias (Norris et al., ).
An important note is that in CER, observational studies of benefits are intended to complement, rather than substitute for, RCTs.
