Risk of Bias Assessment
Captions available
The idea
A systematic review assesses the validity of each included study through a risk of bias assessment.
In practice
Each included trial rated for the specific biases its design was exposed to.
Where people slip
A review that gathered studies without assessing them has synthesised evidence of unknown worth, and the synthesis inherits every weakness it did not look for.
