Plant abiotic resistance in cultivated species features limited variability.
We had limited variability within the categories of some of our parameters (as demonstrated by the small standard deviations in Appendix A), which may have limited the utility of these parameters for predicting our physical exposures.
Data were limited by variability in the types of comparator groups, methodological limitations, and poor reporting of outcomes.
EUS is limited by variability in the examiner's subjective interpretation of B-scan images to differentiate among normal, inflammatory, and malignant tissue.
Understanding tanning motivations, perceptions, barriers, and demographic characteristics of this population is critical to modifying these behaviors, but is limited by variability in study design, sample size, and outcomes measured in the current literature.
11 14 15 These retrospective operative case series report outcomes that are subject to bias, and they are limited by variability in loss of patients to follow-up.
Some insight has been gained from naturally occurring COPD exacerbation studies, but these studies are limited by variability in factors such as time between virus infection and presentation and treatments initiated prior to sampling.
Although the clinical utility of this biomarker in individuals may be limited by variability in baseline levels, in populations chronic OP exposure is associated with small but reliable decreases in erythrocyte AChE activity (Karr et al. 1992; Ohayo-Mitoko et al. 1997).
However, this consistency, which is achieved by limiting sources of variability typically encountered in natural environments, can restrict their utility.
