To explore the reasons for heterogeneity, we considered the diagnostic cut-off point, which may partially explain this heterogeneity because of differences between studies.
Although deposited under similar conditions of high-frequency sea-level fluctuations, these two types of platforms exhibit different internal facies architecture and distribution of heterogeneities, because of differences in base level.
We analyzed stress drops of 686 earthquakes with magnitudes of 4.0 to 5.0 off the south-east of Hokkaido, Japan, and investigated the spatial heterogeneity of the difference between the shear strength and the dynamic stress level on the Pacific Plate.
In particular, the static stress drops of small earthquakes are considered to be good indicators for the heterogeneity of the difference between the strength and the dynamic stress level, because we can assume that the initial stress is equal to the strength at the hypocenter, where the rupture initiates (Yamada et al. 2010).
**Cochran Q test for heterogeneity of prevalence difference (Δ Chart-ICD) between chart review and administrative data across years. 1 Charlson co-morbidities; 2 Elixhauser co-morbidities.
For comparisons of minor arms, significant heterogeneity of the difference between office hour appointments and office hour appointments with the option to change was observed by whether the screening unit was static or mobile (P=0.010) and season of appointment (P<0.001).
When possible, we analyzed the roles of these sources of heterogeneity in explaining differences in results by means of subgroup analysis.
These discrepancies may result from a number of different factors such as the inherent heterogeneity of ASD, methodological differences between studies, comorbid diagnoses and atypical responses to environmental input [31].
The heterogeneity of the observed differences in reported results between the different studies (Table 2) may be explained in part by the differences in the patient populations.
The heterogeneity of patients and differences in the experimental design could explain the divergence of the results such as the inclusion of high risk patients with PEP [ 9] versus patients scheduled to undergo ERCP [ 4, 7, 8].
This may reflect the pharmacologic heterogeneity of LMWH and/or differences in trial design.
