Flatulence

Compared within 1 study that had both: 57 people with flatulence and 34 healthy people. 1 genus is less common in people with flatulence, and none more common.

A difference is an association: it doesn’t mean these genera cause, prevent or treat flatulence. 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 Spain.
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.
