The ICCs' of 57%, 20%and64%4% showed that there was a substantial clustering of wards within nursing homes (see Table 4).
A community-based cross-sectional survey was undertaken using multi-stage cluster sampling of wards and villages.
aχ2 test, b t-test The two-cluster solution produced one cluster of 70 wards and one of 23 wards, whereas the three-cluster solution yielded cluster A with 32 wards, cluster B with 23 wards and cluster C with 38 wards.
The bootstrapping technique [ 21] was used to assess the generalizability of the clustering, and the minimum number of wards per cluster was set at 20 in the replications.
A total of 523 clusters (212 wards and 311 clinics) were included.
The targets of the intervention are the professionals working in the hospital ward, but the outcomes of interest are assessed in clusters of patients from the hospital wards before and after the implementation of the Pac-IFicO programme.
With more than 4,000 patient responders, this was a fairly large-scale study, but the clustering of patients in wards for the purposes of computing wards' average scores meant that the number of measurement units was only 18 wards in two hospital trusts, so its generalisability and statistical power were limited.
During the Mwanza feasibility study, a community liaison system (CLS) was established, based on 78 geographical clusters of facilities in ten city wards [ 34], and has used participatory research tools to facilitate open dialogue and partnership working practices between researchers, study participants and community representatives [ 25].
The results indicate that many high incidence lymphoma wards do occur close together and when computer simulations are used to compute expected results, many of the observed results are shown to be highly improbable both in the overall number of clustering wards and in the largest number of wards comprising a 'cluster'cluster
Average linkage method grouped most of countries in cluster 3 of K-mean method in to other clusters and Wards method merged cluster 3 and 9 of K-mean method in to one cluster (cluster 3).
