Unsupervised PCA analysis revealed a good separation of the two groups when investigating the first two principal components for the results of positive ionization mode (Fig. 2A).
For example, Verle et al. did not find any differences between ethnic groups when investigating the prevalence of intestinal parasitic infections in northern Vietnam (74).
Similarly, we tested if the proportion of DETs changed among phylogenetic groups when investigating the number of DETs relative to the total number of probes represented for each group on the microarray.
This was also done to get comparable groups when investigating the relations between animal exposure to asthma (i.e. comparing the exposed to the unexposed), even if it was likely that housing conditions and diagnostic practices differed to some extent between Finland and Russia.
Since non-resurfaced and resurfaced prostheses generally showed similar results, we did not differentiate between the two treatment groups when investigating possible effects on pain and function of prosthesis brand, sex, age, Charnley Category, time since operation, and preoperative EQ-5D index score (Table 4).
Many authors consider minimal or maximal subgroups of a Sylow subgroup of a group when investigating the structure of (G), such as in [1] and [4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14], etc.

The Glaucophyta are a key algal group when investigating the origin and early diversification of photosynthetic eukaryotes.
Moreover, east coast fishermen's sisters have been found to be more likely to have grown up in a fishing village and/or fisherman's family [ 17], suggesting that they may be a fitting group when investigating health effects due to a high dietary exposure to POPs during childhood and adolescence, or even in utero.
► State schizotypy increased for both groups when intoxicated with cannabis.
