Obesity paradox in patients with community-acquired pneumonia: Have you fully considered the confounding factors?

There exists a notion that there is an obesity paradox in the prognosis of community-acquired pneumonia. In other words, obese individuals with community-acquired pneumonia have a better prognosis. The study by Wang et al supports this claim, but we believe that the obesity paradox should not be proposed hastily as it is influenced by numerous subjective and objective confounding factors.
