Clostridia

Who

12,213 healthy people from 129 studies in GMrepo, by its own “Health” label. Whole-genome sequencing only; one sample is one person.

How common

The share of them whose sample has any of it.

Slice

Its average share of the microbes in a healthy gut, across everyone, carriers or not.

Age and sex

From the samples that record them (about 17% record an age and 29% a sex). A group with fewer than 50 people isn’t shown.

Ranks

A slice’s rank is a place among the genera we have numbers for, within the group shown: exact in the top 10, then rounded bands.

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.

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.
