Abstract:
We read with great interest an article by Karanasos et al. titled "Impact of smoking status on disease severity and mortality of hospitalized patients with COVID-19 infection: a systematic review and meta-analysis".1 It is inferred that there is an adverse impact of smoking on disease severity and mortality of hospitalized COVID-19 patients, which is more pronounced in younger patients without diabetes. Literature is flooded with papers on possible interaction and outcome of COVID-19 association with smoking. However, there are still conflicting views on the effect of smoking in patient outcomes. These conclusions are data-driven and lack valid pathogenetic background for interpretation.
