"Talking of Herbert Spencer," he began, "do you really find no logical difficulty in regarding Nature as a process of involution, passing from definite coherent homogeneity to indefinite incoherent heterogeneity
In particular, we aimed to reveal the underlying mediating mechanism through network relationship strength, and show how this mechanism could be moderated by network heterogeneity
However, there was substantial unexplained heterogeneity
of results across the individual studies ([I.sup.2] = 82%), said Ms.
That puts researchers in a tight position, since techniques that can preserve the heterogeneity
of tumors, such as laser capture microdissection (LCM), also can cause key genetic material--notably RNA--to degrade.
(2012), the study examines how two TMT characteristics, demographic heterogeneity
and value similarity, affect the relationship between task and relationship conflict, as well as between these two types of conflict and various outcomes.
The [I.sup.2] statistic was used to estimate the percentage of variation across studies that resulted from heterogeneity
rather than chance, and an [I.sup.2] value of 50% or higher was taken to indicate significant statistical heterogeneity
Researchers at Karolinska Institute in Sweden have discovered that the risk of death from breast cancer is twice as high for patients with high heterogeneity
of the oestrogen receptor within the same tumour as compared to patients with low heterogeneity
Two previous systematic reviews also suggested that corticosteroids maybe therapeutically equivalent to but safer than NSAIDs, but both were based on a very small number of available studies and were hampered by statistical between-trial heterogeneity
. The meta-analysis of six trials included a total of 817 patients.
influences animal behavior (Wiens and Milne 1989, Crist et al.
testing between studies was conducted using the Cochran Q and [I.sup.2] tests.
The [I.sup.2] statistic was applied to assess heterogeneity
between studies .
Chi-square and I2tests were used to assess the heterogeneity
of the studies.6 The studies in our meta-analysis differed in the design and FSL platform which was the potential source of the heterogeneity
between the studies7 All of the analyses were performed using SPSS 20.
