Relative Risk of Medically Attended Events Between 30-day Risk Window and 30-day Self-control Window: Pre-Dose 1 Inpatient

Relative risk for given event=incidence rate(risk window)/incidence rate(self-control window).Relative risk in inpatient health care setting for pre-dose 1 assessed by comparing incidence rate of reported events in inpatient setting/1000 person-months occurring within 30 days after Dose 1(30-day risk window) with self-control period occurring during 30 days before Dose 1(pre-vaccination 30-day self-control window).Relative risk,exact 2-sided 90 percent (%) confidence intervals (CIs) reported. Medically attended events documented retrospectively according to International Classification of Diseases, ninth Revision (ICD-9) coding.Medical attended event acute bronchiolitis due to Respiratory Syncytial Virus (RSV) has been represented as acute bronchiolitis due to RSV and acute pyelonephritis without renal medullary necrosis(RMN) lesion has been represented as acute pyelonephritis without RMN lesion in measure categories below.Results reported for events reported in either of the windows.
