Definition
The original Paley framework describes a problem as a difficulty resolved without surgery, an obstacle as one requiring surgery but resolved by the end of treatment, and a complication as a difficulty or sequela that remains. Later authors have modified, combined, or replaced these categories. A percentage reported under one version is therefore not automatically comparable with a study using another definition or denominator. [1][2]
