The results were organized into the following mutually exclusive groups for comparison: domestic cat studies, big cat studies, and small cat studies excluding domestic cats (i.e. small exotic cats).
This study was conducted to define diversity and community structure of ground-dwelling spider species in agricultural field margins and to propose potential biological indicator species or groups by focusing on dominant groups for comparison of biodiversity among habitats.
We stratified patients 16 55 years of age into four age groups for comparison and used multivariable logistic regression to identify associations of potential susceptibilities and exposures with AKI and mortality.
The focus on Ethiopian Somalis is an entry-point into broader considerations of the relationship between homeland politics and diaspora identities, using some of Ethiopia's other prominent ethnic groups for comparison.
The amount of graft within the tunnel was arbitrarily divided into groups for comparison (≤1.5, ≤2, or ≤2.5 cm) because the minimum graft length necessary for proper integration is not specified in the literature [16].
