heterogeneity

"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.

(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.

Environmental heterogeneity influences animal behavior (Wiens and Milne 1989, Crist et al.

Heterogeneity 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 [25].

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.
