The top 20 enriched biological processes across, colored by p-values (the darker the color, the more statistically significant). (a) 186 differently abundant PGs (p < 0.05) from the comparison of controls vs. NW. Changes were mainly associated with cell adhesion and protein folding and platelet activation, signaling, and aggregation. (b) A total of 122 differently abundant PGs (p < 0.05) from the comparison of ICU (A+B+N) vs. NW. This comparison showed the most significant association with protein folding and cell adhesion and platelet activation, signaling, and aggregation. (c) A total of 116 differently abundant PGs (p < 0.05) from the comparison of ICU B vs. NW. Over time, the survivors showed changes associated with platelet degranulation and protein folding. ICU: intensive care unit (ICU A: non-survivors, ICU B: survivors, ICU N: unknown); NW: normal ward.
