Epigenetic age acceleration in survived versus deceased COVID-19 patients at the end of follow-up (FU) timepoint. Boxplots of DNAm age acceleration measured using six epigenetic clocks (a–f) in the peripheral blood from 50 surviving versus 14 deceased COVID-19 patients at the end of follow-up. The y-axis denotes the epigenetic age acceleration. p value is shown above the corresponding line. In the box plots, the lower and upper hinges indicate the 25th and 75th percentiles and the black line within the box represents the median. ns: non-significant
