Description of intervention(s) / exposure
Coronavirus disease 2019 (COVID-19) caused by the virus SARS-CoV-2 defines as a pandemic respiratory infection that causes fever, cough, dyspnea, and pulmonary interstitial damage. Unfortunately, SARS-CoV-2 is fastly transmittable between humans and has affected approximately 17.6 million people worldwide. As of July 2020, the World Health Organization (WHO) reported around 425000 confirmed cases in Mexico. In Tabasco, a state of the southeast of Mexico has reported 21300 cases for COVID-19.
The "Dr. Juan Graham Casasús" Hospital received nearly 3000 patients during the pick of the pandemic. Therefore, this proposal is based on the outcomes of hospitalized patients by COVID-19 in Tabasco. This retrospective study will evaluate the medical records of patients diagnosed with COVID-19 in a third-level hospital in Tabasco, from admission until discharge/death.
We will collect sociodemographic, comorbidities, and clinical symptoms at admission, then pharmacological treatment, and laboratory data.

Statistical methods / analysis
First, all data will be analyzed by the descriptive statistic.
To describe demographic, clinical, and laboratory variables will be used a frequency distribution, central tendency, and dispersion, according to the case.
Second, we will compare all variables in survivor and non-survivor patients. Categorical variables will compare using the x2 test or Fisher’s test., Quantitative variables will be compared using the t-test.
Third, multiple logistic regression will be used to identify predictors of mortality.
All analyses will be processed by SPSS for windows version 21.0.

Summary
Brief summary
SARS-CoV-2 is fastly transmittable between humans and has affected approximately 17.6 million people worldwide. As of July 2020, the World Health Organization (WHO) reported around 425000 confirmed cases in Mexico.
In Tabasco, a state located in southeast Mexico reported 21300 cases for COVID-19. It is noteworthy that "Dr. Juan Graham Casasús" Hospital is the most important for the COVID-19 attention in Tabasco. Hence, the present study aims to determine the sociodemographic, clinical, imaging features, and biochemical levels of adult survivors and non-survivors of COVID-19 infection treated at the "Dr. Juan Graham Casasus" Hospital in Tabasco, Mexico.
So the retrospective analysis of the epidemiology and clinical features in patients with COVID-19 contributes to the scientific actualization of clinical work carried out during the pandemic.
