Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Correlation of Microbiome to Psoriasis via Relative Abundance Found in Microbiome Sequencing	Relative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be correlated with specific Psoriasis types	1 year

Secondary Outcomes

Measure	Description	Time Frame
Validation of Sequencing Methods	To validate the methods used to sequence samples	1 year
