Note. Outcomes rated by the expert panel as being most important with a mean rating greater than 7 and a median rating greater than or equal to 8 were designated as core for measurement and reporting by BWMIs.

Abbreviations: BMI, body mass index; QoL, quality of life.

^aMean scores were not greater than 7 and/or median scores were not greater than or equal to 8, but outcomes are considered protected characteristics.

^bNew outcome added to ensure a comprehensive core outcome set.
