But when the researchers did a statistical analysis that eliminated the effect of study design, the disparities were no longer apparent.
Regression analysis was used to establish the combined effect of study variables on the dependent variable.
Interestingly, previous reports have identified the opposite effect of study realization time in other forms of ECMO for cardiovascular support, in which mortality increased with publication year [12].
There was no significant effect of study design, gender, age, type of meal ingested, exercise intensity, exercise duration, or timing of exercise on the postprandial response (P >.05).
We systematically explore the effect of study design and spatial variability of 137Cs on the sensitivity of the radiocaesium technique for soil erosion studies.
Simple statistics, correlation, linear regression and mixed model analysis assessing the random effect of study were used to describe the relationships between rumen and production parameters.
The objectives of the study were to identify associations supported by current evidence and to investigate the effect of study design on reporting associations.
To investigate the effect of study duration, we have fully analyzed the dataset twice, once including only data acquired over the first 0 2.5 h p.i. and once including the full 0 4.5 h data.
Clines, Clusters, and the effect of study design on the inference of human population structure.
To evaluate the effect of study design on SRHS we conducted five analyses.
Violation of HWE in multivariable regression analysis remained a statistically significant source of heterogeneity after adjustment for the effect of study size (PHet = 0.031, τ2 = 0.020).
