Study design details

Main study objective

To assess whether there is an increased risk of new-onset Guillain-Barré Syndrome (GBS), Gout, Polymyalgia Rheumatica (PMR), Giant Cell Arteritis (GCA), Ischemic Optic Neuropathy (ION) or Supraventricular Tachycardia (SVT) within specified time periods after RZV vaccination in people ≥ 50 years of age enrolled starting in January 2018 at any of the participating U.S. Research Partners.

Outcomes

The risk of new onset GBS (within 42 days) and Gout (within 30 days) following RZV vaccination using a Self-controlled Risk Interval (SCRI) design and the risk of new onset PMR (within 183 days) and GCA (within 183 days) following RZV vaccination using a cohort design. The risk of new onset SVT within 30 days following RZV vaccination using a SCRI design and the risk of new onset ION within 183 days following RZV vaccination using a cohort design.

Data analysis plan

The analysis plan includes descriptive measures to characterize exposed and unexposed individuals, conditional Poisson regression models for the SCRI, and Cox proportional hazards regression models for the cohort design outcomes Sentinel analytic tools will be used for the distributed analyses, modifications to the tools may be needed to meet study objectives. For each outcome there is a primary analysis, secondary analysis and sensitivity analysis. All the statistical calculations will be done in SAS 9.2 or higher.
