Slide 8
"Out of 21 patients in the extension study, microbiota analysis was performed on 16 patients who consented to stool sampling (1 patient withdrew from study, 4 patients did not consent."

So there are 20 patients remaining in the extension study. Considering the demographic they belong to, I'd say that's astounding.

Assuming you'll even bother to click on the link this time, while you're there, check out the p-value between the low blood concentration group and the high concentration group. The larger the sample size the easier it is to get a p-value that indicates the difference between the groups is unlikely to be due to chance. The smaller the sample size the harder it is to get a p-value that indicates the difference between the groups is unlikely to be due to chance.
