Finally, we were not able to include use of antidepressants as a variable in the analyses because of variability in dose, type of medicine, timing of any changes, and lack of measuring adherence.
Because of variability in each group, it was not possible to associate hyperthyroid cats and total PBDE levels.
Because of variability in outcomes, meta-analyses included a maximum of 4 studies.
These differences may, in part, be because of variability in identification of endoscopic criteria.
Results varied by year, in part because of variability in growing season rainfall and in part because of variations in water allocations.
Transpiration of urban forests in southern California is highly uncertain and challenging to quantify because of variability of tree characteristics and stomatal responses among species and locations.
This may be because of variability in existing plans and a failure to consider visual design and usability factors in plan development.
Because of variability in lipoprotein cholesterol content, low-density lipoprotein (LDL) cholesterol frequently underrepresents or overrepresents the number of LDL particles.
The turbine operates in a narrow range because of variability in waves, machine geometry and low incidence angle that lead to stumpy performance of the turbine.
Because of variability in toxicity assessment, prior rates of toxicity may not be reliable when evaluated against a phase II study focusing on toxicity amelioration.
Because of variability of the force vs. penetration relationship (FPR) from one blow to another in percussive drilling, and difficulty to predict FPRs under such conditions, use is commonly made of simple FPR models, such as the bilinear one defined by its loading/unloading slopes.
