The dataset provided by SESAB contained a total of 154,868 patients that were detected with COVID-19 in the state of Bahia, Brazil. After removing the patients with invalid data (e.g., notification year prior to 2020, length of hospital stay lower than zero, age lower than zero, unknown outcome), the dataset contained a total of 118,011 patients with valid registration. Finally, we removed the patients that were not admitted to a hospital, restricting our evaluation to a final count of 3,896 patients.
