Substantial underestimate of baseline numbers: the authors state that ‘in the years 2011–17 there were 13 628 admissions with patients aged 16+ years with a fracture of the upper humerus’. This is a substantial underestimate. Inspection of the diagnosis table (primary diagnosis S42.2) for 2016–17 (accessed via: https://digital.nhs.uk/data-and-information/publications/statistical/hospital-admitted-patient-care-activity/2016-17) shows there were 18 172 episodes and 12 823 admissions for this 1-year period.
