Alternatives: "are often examined" or "are regularly evaluated."
Pharmaceutical residues in water are frequently analysed and discussed in connection with sewage treatment, ecotoxicity and, natural and drinking water quality.
The impact of trawling on benthic animals has traditionally been analysed by changes in species composition and abundance, whereas frequency and distribution of trawl tracks are frequently analysed by side-scan sonar.
These two subscales correlate highly and HADS scores are frequently analysed as a single scale (Bjelland et al, 2002).
Although these outcomes are frequently analysed with a linear mixed model, or a Poisson mixed model, a two-part mixed model would be better in analysing outcome variables with an excess of zeros.
While the demand function for first-time buyers is frequently analysed, the fact that Americans make their largest home purchase at the average age of 45 is rarely considered.
Although the sequence requirements for translation initiation regions have been frequently analysed, usually the highly expressed genes are not treated as a separate dataset.

Beyond its use in formal classification systems, tumour cell proliferation is frequently analysed by pathologists to comprehensively describe the aggressiveness and the biological behaviour of a tumour which may provide additional 'non-formalised' clues for therapy selection.
By means of a quality control check that is commonly performed at the beginning of studies, ASC were frequently analysed for CD34-negativity, since the absence of this marker is a prerequisite to meet the minimal criteria for multipotent mesenchymal stromal cells (Refs 25, 47).
Count variables are most frequently analysed using Poisson regression but the Hurdle model [ 14] is a proper method to handle excess of zeros and/or the overdispersion in the data.
