Incidence, prevalence, and comorbidities of chronic pancreatitis: A 7-year population-based study

Figure 1 Flowchart of the inclusion and exclusion processes. A total of 61112 electronic records from 38296 patients with a diagnosis of chronic pancreatitis were retrieved from the Health Information Center of Sichuan Province. A total of 3180 records were excluded due to missing encrypted patient identification numbers (1518 records) and conflicting information (1662 records from 206 individuals). A total of 57932 electronic records from 38090 unique patients with chronic pancreatitis were ultimately included in this study.
