Specify any assessment of risk of bias that could impact the cumulative evidence (which include publication bias, selective reporting in experiments).

Sensitivity analyses are accustomed to take a look at the degree to which the primary conclusions of a systematic overview are influenced by improvements in its approaches or in the information employed from specific studies (for example study inclusion conditions, outcomes of possibility of bias evaluation).
