Type 2 diabetes is common and its prevalence is increasing worldwide. And it is associated with a range of complications - from heart disease to kidney disease to stroke.

So it is important that we get the diagnosis and management of this condition right.

The purpose of BMJ Best Practice is to help get evidence into practice.

We use GRADE to ensure that we use the highest quality evidence. GRADE helps us to assess evidence for risk of bias, inconsistency, indirectness, imprecision, and the degree to which it may be subject to publication bias.

To find out what all these things mean, please do listen to this podcast with Dr Anna Ellis, Head of Editorial at BMJ Digital Health.
