Title: Association of BCG vaccination policy with prevalence and mortality of COVID-19 Document date: 2020_4_6
ID: 93b2ivio_7
Snippet: The country's BCG policy was the independent variable (IV) of interest. In accordance with the BCG world atlas 12 , this variable had three levels: Group A, the country currently administers the BCG; Group B, the country used to administer the BCG and currently does not; and Group C, the country has never administered the vaccine. The country's life expectancy and mean temperature (°C) in February and March 2020 were added as control variables i.....
Document: The country's BCG policy was the independent variable (IV) of interest. In accordance with the BCG world atlas 12 , this variable had three levels: Group A, the country currently administers the BCG; Group B, the country used to administer the BCG and currently does not; and Group C, the country has never administered the vaccine. The country's life expectancy and mean temperature (°C) in February and March 2020 were added as control variables in all the models in order to rule out potentially confounding effects. In fact, infection rates and mortality rates may have been influenced by the subject's age (i.e., the older, the more vulnerable) and climate conditions (i.e., the higher the temperature, the less contagious the virus).
