Figure 5. Patients with shorter telomeres develop more severe COVID-19 disease. (A) The telomere lengths of patients were distributed into the quartiles <25% (<11.68 kb), 25-75% (11.68–14.96 kb) and >75% (>14.96 kb) and correlated with COVID-19 severity. (B) The abundance of short telomeres was distributed into the quartiles <25% (<14.73%), 25-75% (14.73-19.32%) and >75% (>19.32%) and correlated with COVID-19 severity. Data represent mean values ±SEM. Statistical significance was assessed using Student’s t test.
