Sepsis

Compared within 1 study that had both: 103 people with sepsis and 206 healthy people. 5 genera are less common in people with sepsis, and 5 more common.

A difference is an association: it doesn’t mean these genera cause, prevent or treat sepsis. GMrepo reports this group at the genus level only, so these are genera, not species.

Searching opens both lists and shows only matching rows.

Where these numbers come from

Studies
Only GMrepo projects that had people with the condition and healthy people, 10 or more of each. Numbers come from those studies, never from pooling.Sampled in the United States.
How common
The share of people whose sample has any of it, in the people with the condition and in the healthy people of those same studies. Tested within studies (Cochran–Mantel–Haenszel, corrected for testing many microbes); a difference counts when it is clear and meaningful (Cohen’s h of 0.2 or more).
Strength word
Counted by code from how many studies point the same way: Seen again and again (3 or more, none clearly the other way), Seen more than once (2, the majority), Seen once (1, listed last). Where studies disagree, a row isn’t listed.
Each study
Tap a row for every study’s own numbers, and for how much carriers have.
