Investigation of the sudden unexpected deaths (SUDs) during COVID-19 pandemic focusing on SARS-CoV-2-positive patients

The study included all the deceased participant’s demographics, case history, and SARS-CoV-2 testing results that were entered into an Excel sheet and analyzed using STATA and EpiInfo. Deceased participants were given a unique study identification code. The variables were grouped and presented as frequencies and percentages, with (OR) values comparing the Delta wave period and the Omicron wave period as descriptive statistics. The Odds ratio (OR) of testing positive for SARS-CoV-2 during the two waves associated with sudden and unexpected death as the outcome was calculated using EpiInfo (version 7.2.0.1) Software using Fisher’s exact test. The odds ratios of each variable and the p-value for statistical significance were determined.
