Outcome: remission of type 2 diabetes within 1 year
Parameters prior to surgery:

where:
• The intercept for the prediction model is not supplied.
Interpretation:
• minimum number of risk factors for persistent diabetes: 0
• maximum number of risk factors for persistent diabetes: 4
• A person with no risk factors has a greater chance of remission.
