Telomere length in hospitalized COVID-19 patients and healthy controls. A TL in Kb as determined by PCR in healthy controls (CTRL; blue, n = 169) and COVID-19 patients (red, n = 251) plotted against age. TL/age correlation coefficient by Spearman rank test: COVID-19 r = 0.1 p = 0.10, CTRL r = 0.46 p < 0.0001. B TL Z-score of healthy controls (blue) and COVID-19 patients (red). Median and IQR [25, 75%] are represented. C TL Z-score in COVID-19 patients by age groups, younger or older than 55 years-old
