Necessary Rewording for Clarity

Throughout the article, some sentences required rewording:

1. In the ‘Data Collection’ section:

Each hospital provided the following information at the beginning of the study: estimated size of population served, total number of beds, number of intensive care unit (ICU) beds, number of ventilators, number of cardiologists, availability of echocardiogram (ECG) and advanced care interventional and diagnostic capability (e.g., extracorporeal membrane oxygenation [ECMO], echocardiography [ECHO]), and number of COVID-19 patients admitted in the previous month.

Becomes:

Each hospital provided the following information at the beginning of the study: estimated size of population served, total number of beds, number of intensive care unit (ICU) beds, number of ventilators, number of specialists, availability of echocardiogram (ECG) and advanced care interventional and diagnostic capability (e.g., extracorporeal membrane oxygenation [ECMO], echocardiography [ECHO]), and number of COVID-19 patients admitted in the previous month.

2. In ‘Ethical Considerations’ the following sentence was added: ‘Mandated national regulatory clearances were also obtained.’ 3. In ‘Results’:

Non-survivors more often presented with significantly higher heart rate, lower diastolic blood pressures, shortness of breath and more frequently had hypertension, diabetes, coronary heart disease, atrial fibrillation, rheumatic heart disease, Chagas disease, valvular disease, and chronic kidney disease (Table 2b).

Becomes:

Non-survivors more often presented with significantly higher heart rate, lower diastolic blood pressures, shortness of breath and more frequently had hypertension, diabetes, coronary artery disease, stroke, chronic kidney disease, chronic pulmonary disease, asthma and renal replacement therapy. (Table 2b).

4. Further on in the same section, ‘ECG examinations (n = 3497 patients; 65.8%) indicated that 2.5% had atrial fibrillation’ was corrected to ‘ECG examinations (n = 3490 patients; 65.8%) indicated that 2.5% had atrial fibrillation’. 5. In the ‘Discussion’ section, the following passage was reworded from:

Our analysis demonstrated a greater rate of in-hospital deaths, post discharge 30-day deaths and MACE among Hispanics, and Asian populations compared to Caucasians. Higher prevalence of comorbidities such as hypertension, diabetes, renal disease and obesity among Asians, Hispanics, and other populations (such as Blacks and Middle Eastern populations) may play a role in the increased mortality and MACE in our cohort of COVID-19 patients.

To:

Our analysis demonstrated a greater rate of in-hospital deaths, and post discharge 30-day deaths among Hispanics, Asian, Blacks and Middle Eastern populations compared to Caucasians. Higher prevalence of comorbidities such as hypertension, diabetes, renal disease and obesity among Asians, Hispanics, Blacks and Middle Eastern populations may play a role in the increased mortality and MACE in our cohort of COVID-19 patients.

6. In ‘Conclusions’, the following sentence: ‘The key predictors of mortality or MACE outcomes were older age (≥60 years), male sex, Asian/Hispanic/Black ethnicity, pre-existing coronary heart disease, diabetes, renal disease, severe infection of COVID-19 requiring ICU admission, oxygen therapy and higher respiratory rates, but no significant association was found with hypertension or RAAS inhibitors.’ Was corrected by removing ‘or MACE outcomes’. 7. In the ‘Steering Committee’ section, Karen Sliwa (study Co-PI), Dorairaj Prabhakaran (Study Co-PI), Pablo Perel (co-PI), should all have had the same role title of ‘Study Co-PI’.
