There were no statistically different RAGE, sRAGE and HMGB-1 levels found during early CAP-associated sepsis in ARDS or non-surviving patients ( Figure 1C , Figure 1E , Figure 2A and Table 2 ). No difference was found between influenza A H1N1 infected patients and the rest of the study group (2767 ± 1655 vs 2174 ± 1344, P = .327). We did not find a correlation between immunological molecules and severity assessment scores using Spearman's correlation coefficient (P value range = .16-.99). Finally, none of the studied severity assessment scores correlated with each other (P value range = .18-.79).
