Fig 1.
Data collection and statistical analysis of the RSV model-based study conducted in Japan, 2015–2018.
a: Hospitals participating in the Diagnosis Procedure Combination system, which are mostly acute care hospitals; b: Data were captured from 1 January 2015 until 30 June 2019, to exclude the impact of the COVID-19 pandemic on RSV epidemiology; Abbreviations: DPC, Diagnosis Procedure Combination; ICD-10, International Classification of Diseases, 10th Revision; RSV, Respiratory Syncytial Virus.
