1. Summary of the results
The available analyses provide varying insights into the percentage of COVID-19 deaths due to sole COVID-19 infection without comorbidities in 2020. According to [1], for over 5% of COVID-19 deaths, COVID-19 was the only cause mentioned on the death certificate, implying that these deaths were due to sole COVID-19 infection without comorbidities [1]. However, [2] and [3] do not provide a direct percentage of COVID-19 deaths due to sole COVID-19 infection without comorbidities, with [2] stating that 20.3% of deceased patients and 30.4% of living patients had no comorbidity information recorded [2], and [3] analyzing the mortality rate of COVID-19 patients based on underlying health conditions [3]. Furthermore, [4] reports that in an Indonesian hospital study, all 78 COVID-19 deaths had at least one comorbidity, resulting in 0% of the deaths being attributed to sole COVID-19 infection without comorbidities [4]. The CDC webpage, as mentioned in [5], lists underlying conditions that increase COVID-19 severity but does not provide a specific percentage of 2020 deaths that occurred without any comorbidities [5]. Additionally, [6] examines the impact of cardiac and pulmonary comorbidities on mortality but does not report the proportion of deaths occurring in patients without any comorbidities [6].
2. Missing context/alternative viewpoints
Key omitted facts include the lack of direct percentages of COVID-19 deaths due to sole COVID-19 infection without comorbidities in most analyses, such as [2] and [3] [2] [3]. Moreover, the Indonesian hospital study [4] and the Romanian cohort study [6] provide insights into specific populations, which may not be representative of the global situation. Alternative viewpoints could consider the impact of age and comorbidity interactions on COVID-19 mortality, as mentioned in [6] [6], as well as the role of underlying conditions in increasing COVID-19 severity, as listed on the CDC webpage [5]. The benefits of considering these alternative viewpoints would be to healthcare professionals, who could use this information to better understand the risks and develop targeted treatment strategies, and to researchers, who could design more comprehensive studies to address the gaps in current knowledge [2] [1] [3] [4] [5] [6].
3. Potential misinformation/bias in the original statement
The original statement may be misleading due to the lack of clear data on the percentage of COVID-19 deaths due to sole COVID-19 infection without comorbidities. The analyses provided, such as [1], suggest that this percentage may be relatively low, with over 5% of COVID-19 deaths having COVID-19 as the only cause mentioned on the death certificate [1]. However, other analyses, such as [4], report that all deaths in a specific study had at least one comorbidity, resulting in 0% of the deaths being attributed to sole COVID-19 infection without comorbidities [4]. This discrepancy highlights the potential for misinformation or bias in the original statement, which may be influenced by the selection of data sources or the interpretation of results. The benefits of this framing would be to those who downplay the role of comorbidities in COVID-19 deaths, while the drawbacks would be to public health officials and researchers who rely on accurate data to inform their decisions and studies [2] [1] [3] [4] [5] [6].
