The logistics issues related to availability of students during pre-planned academic activities constrained the sample size.
Available time and funding constrained the sample size, limiting the inclusion of a potentially broader range of perspectives.
These data from our 4 year study must still be interpreted cautiously, constrained by sample size, the sensitivity of swab testing, and the finding that individuals of some susceptible species may carry fluctuating low-level infection (Briggs et al., 2010).
In practice however, the value of τ is constrained by sample size because the genotype contingency tables for combinations rapidly become sparse and contain numerous empty cells when the order of the combinations increases.
However, a three-group (ɛ4-homozygote, ɛ4-heterozygote, and noncarriers) analysis to confirm that PA can enhance cognition at age ≥ 70 years regardless of genotype group was constrained by sample size.
6 7 16 17 Although these studies provided useful insights into risk stratification, most were constrained by relatively small sample sizes, reliance on surrogate outcomes, or lack of accurate tools to evaluate RV size and function.
Previous large-scale, population-based studies mainly focused on GI symptomatology in DM (2, 8), whereas endoscopic studies reporting GI pathology in DM were constrained by relatively small sample sizes or the enrollment of mostly symptomatic diabetic subjects (9– 12).
It avoids linear model fitting and thus is more efficient and less constrained by the sample size.
The results are constrained by the sample size.
Previous attempts at global metabolic characterization of the date metabolome were constrained by small sample size and limited geographical sampling.
