Comparison of protein putrefaction products among the cohorts.

<p>Box plots depicting relative metabolite abundance are shown, as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0119362#pone.0119362.g008" target="_blank">Fig. 8</a>. A) Among the endoscopy collected samples, with the exception of methyl indole, the metabolites are comparable in abundance within the healthy and alcoholic cohorts. Note however, the difference observed with methyl indole is not statistically significant (<i>p</i> = 0.519). B) In the home collected samples, metabolite abundance is very similar between the healthy and alcoholic fecal samples.
