The former result probably occurred when only a part of total heterogeneity was sampled with a small ring.
The fact that swabbed area explained between 56 and 62% and total sample size between 23 and 38% of the total heterogeneity in the chilling true effect size, indicates that differences in experimental design greatly affect our substantive conclusion about the effect of chilling on Salmonella occurrence.
A total heterogeneity statistic, which tests for heterogeneity in effect sizes between studies, was also produced (Appendix S3, Equation 4).
In addition to estimating confidence intervals, MetaWin also estimates total heterogeneity (between-sample variance) and tests its significance with the χ2 distribution using n-1 degrees of freedom.
In smoking-unadjusted estimates, period also accounted for a large proportion (46.9%) of the total heterogeneity.
Thus the total heterogeneity present is very much a product of this single trial.

In addition, although the small size of a tissue biopsy may not reflect the total genetic heterogeneity within the disease, EVs shed from heterogeneous cancers reflect the dynamic changes that occur during disease and allow us to access crucial molecular information about the status of diseases.
If a substantial proportion of the total observed heterogeneity is successfully 'explained' by the analysis, then the F-ratio comparing 'between group' to 'within group' heterogeneity should be large; the observed value may be compared to the corresponding F distribution to establish whether it is larger than could reasonably be expected by chance.
The proportion of the total spatial heterogeneity explained by the spatially structured conditional autoregression term was 73.2 %.
Lastly, the proportion of spatially explained variance was calculated as the proportion of total spatial heterogeneity accounted for by the spatially structured conditional autoregression variance.
9.6% TSH for G. nesiotis compared with G. comeri ( = Total Sequence Heterogeneity [15], [14]) versus 2.1% and 0.3% TSH for tRNA-Lys/ATP synthase subunit 8 (and8) and cytochrome b, respectively.
