Study design details

• Study design:
  - New drug user cohort study; - Population-level cohort study
• Main study objective:
  The main objective of the study is to determine the dose, formulation, cumulative duration and setting at time of treatment initiation of any of the prokinetic drugs of interest for patients diagnosed with gastroparesis and to determine the incidence and prevalence of use of medications with prokinetics properties in patients diagnosed with gastroparesis, in children and adults separately.
• Data analysis plan:
  Patient-level drug utilization: Large-scale patient-level characterization will be conducted at index date including patient demographics, comorbidity and medication. Cumulative duration of use of medication with prokinetic properties, dose, formulation and different types of setting will be reported. Population-level utilization of medication with prokinetic properties: Annual period prevalence of the use of medications with prokinetics properties and annual incidence rates per 100000 person years will be estimated. For all analyses a minimum cell count of 5 will be used when reporting results, with any smaller counts obscured.
