Like all meta-analysis, we must consider limitations with combining estimates from different studies because of clinical heterogeneity such as differences in populations of patients, even with statistical adjustments in the analysis.
Numerical differences in populations of V. dahliae could mean that fungal antagonists are partially involved in delaying increase of V. dahliae and prolonging the effectiveness of the method.
This test experiment demonstrated that we can distinguish differences in populations of each tagged mutant within pools by quantifying the signature tags.
The discordance in results among studies could be caused by contextual factors (differences in populations of patients and usual practice within units) or intervention factors (differences in determining readiness to wean, ventilator modes, and variables used in weaning protocols).
28 Our exploratory analysis did not identify autism as a modifier of treatment effect, suggesting the differences in the size of effect are not explained by differences in populations of patients.
Much of the variation in reports of prevalence is likely due to the differences in populations of cattle studied, which include the type of operation (beef versus dairy), age distribution of cattle, and variation in management practices [ 22].
Essentially, there were no appreciable differences in populations of effector T-cells, including CD4+ and CD8+ T-cells, various differential stages of B-cells, including CD21+, sIgM+, sIgD+ and CD23+ cells, and NK (natural killer) (NK1.1+) cells.
FACS analysis using anti-F4/80 (a macrophage marker), anti-CD3 (a T-cell marker) and anti-CD19 (B-cell marker) antibodies also showed no significant difference in population of those cell types infiltrated into lungs between WT and Ninj1 KO mice (Supplementary Fig. S3).
This may explain the significant difference in population of the g p _ chel structure between series b and c.
In addition to differences in susceptibility or the specific composition or extent of exposures, these inconsistencies might also be a consequence of differences in population measurement of CIMT, statistical models, adjustment sets, or exposure assessment.
