Symptoms Evaluation After Anti-Reflux Surgery—Gi Perspective

Abstract

The objective of the study was to measure the extent in which the percentage of fully vaccinated individuals during the dominant periods of Alpha, Delta, and Omicron variants have influenced mortality rates. This study was conducted using COVID-19 Centers for Disease Control and Prevention (CDC) Case Surveillance Public Data Taskforce for 57 states and United States territories between January 1, 2020 to March 20, 2022. Multivariable binary Hyperbolastic regression of type I was used to analyze the data. Seniors and ICU-admitted patients had the highest risk of death. For each additional percent increase in fully vaccinated individuals, the odds of death deceased by 1%. The odds of death prior to vaccine availability, compared to post vaccine availability, was 1.27. When comparing the time periods each variant was dominant, the odds of death was 3.45-fold higher during Delta compared to Alpha. All predictor variables had P-values less than .001. There was a noticeable difference in the odds of death among subcategories of age, race/ethnicity, sex, PMCs, hospitalization, ICU, vaccine availability, variant, and percent of fully vaccinated individuals.
