The Effects of Non-pharmaceutical Interventions on COVID-19 Mortality: A Generalized Synthetic Control Approach Across 169 Countries

S. Mader and T. Rüttenauer

Explore the findings of Sebastian Mader and Tobias Rüttenauer, who conducted a decisive study on the effects of non-pharmaceutical interventions (NPIs) on COVID-19 mortality across 169 countries. Discover the surprising lack of substantial benefits from most NPIs and learn how COVID-19 vaccination emerged as a significant factor in reducing fatalities.

Abstract
This study investigates the impact of non-pharmaceutical interventions (NPIs) on COVID-19 mortality across 169 countries from July 1, 2020, to September 1, 2021. Using a generalized synthetic control (GSC) method and controlling for various factors, the researchers find no substantial or consistent fatality-reducing effects of most NPIs. While a tentative trend change was observed after implementing strict stay-at-home rules and workplace closures, these effects were not statistically significant. In contrast, the study successfully demonstrates a significant fatality-reducing effect of COVID-19 vaccination using the same methodology.
