Captions available
The idea
Bias can be introduced at every stage of a study — in who takes part, in what is done to them, in how outcomes are measured, and in what is reported.
In practice
A study sound in design and biased in its measurement.
Where people slip
Finding one source of bias does not mean you have found the bias. Each stage is checked separately.
