Methodological quality

Interpretation

Within a study

Across studies

Low

Bias may seriously weaken confidence in the results.

The criteria was not met in one or more of the quality domains.

Most information was from low quality studies.

Moderate

There is a risk of bias that raises some doubt about the results.

The criteria was met, or there was not enough information to judge if the criteria was met for all quality domains.

Most information was from high or moderate quality studies.

High

Bias, if present, is unlikely to alter the results seriously.

The criteria was met in all the quality domains.
