Fig. 8From: DNA methylation predicts the outcome of COVID-19 patients with acute respiratory distress syndromeHeatmap representing significant changes in CpGs between patients who died and those who recovered over four time points. Heatmap represents methylation beta values which were Z-score transformed (the euclidean clustering distance and Ward.D2 clustering methods were used). Details on these CpGs are shown in Additional file 7: Table S7BBack to article page
