In the stratified analyses, heterogeneity between studies was reduced, suggesting that the varied data collection method, recruitment setting, sample size, study time and study locations may account for the inconsistency among studies.
2– 5 However, gender distribution may vary geographically and recent data suggest that while in Europe and North America IBS has a higher prevalence in women than in men, in Africa, southern Asia and South America, the prevalence of IBS may be similar in both genders.
While all α-synucleinopathies are characterized by α-synuclein aggregates with similar posttranslational modifications and lipid associations, the cell type involved, their location and their association with other protein depositions vary substantially, and recent data suggest that perhaps the strain of α-synuclein involved may also differ.
In addition, the expression of the 47 kDa and 51 kDa isoforms varied over time; thus, these data suggest that both isoforms play different roles in HCC progression.
The procedure for collection, pretreatment, storage, and preparation of the placenta prior to analysis varied among studies, although available data suggest that such processes may influence the magnitude and comparability of the trace metal concentrations (Khera et al. 1980; Lagerkvist et al. 1996).
Expression of ALMS1 varies between tissues and recent data suggest that its transcription is modulated during adipogenesis and growth arrest.
However, qualitative analyses of our data suggest that children vary in their abilities and speed to learn and apply NF techniques.
Although assessment and definition of disease progression vary across studies, the current clinical data suggest that ESAs may have little effect on disease progression in chemotherapy patients, and preclinical data indicate a direct or indirect effect of ESAs on tumour growth is not strongly supported.
Our data suggest that climate change varies by region and season and is not a simple case of species responding to consistently increasing temperatures across the region.
On a year-to-year basis, the exact seeding location may vary (Bahl et al. 2011), but data suggest that some strains circulate around the globe and persist for multiple years (Bedford et al. 2010; Bahl et al. 2011).
