Discuss Respiratory Tract Dysbiosis Is Associated with Worse Outcomes in Mechanically Ventilated Patients

From BugSigDB

The sample sizes of the subgroups (hyper-inflammatory subphenotype, VFD, mortality) with negative cultures were not explicitly stated. Therefore, I used the sum of the 2 main groups (those with negative cultures and those whose cultures were not obtained) as the sample sizes for the 2 groups. I interpreted the shannon diversity as an increase for groups with more hazard taxa, and as a decrease for groups with more positive taxa
