Closed and open-reference OTU picking yielded similar β-diversity results. Three pairs of studies were separately analyzed using the two OTU picking methods and then compared using Procrustes analysis. Each point is the result of open-reference OTU picking, and each arrowhead is the same sample from closed-reference OTU picking. A significant Procrustes statistic indicates that the results from β-diversity analysis are strongly correlated. The same sample across the two methods are linked with an arrow. a California dairy and neonatal intensive care unit, both near Davis, California; b North Carolina homes in and near Raleigh, North Carolina, and Boulder, Colorado residential kitchen surfaces; c Oregon classroom air and surface samples from Eugene. Although the California Dairy study appears to be different between the two methods (a), the Dairy site was statistically distinct from the paired NICU study regardless of OTU picking method
