In general, the associations found in the total series were upheld in these sub-set analyses.
Patients who had received stem cell transplants (SCT) were identified from a separate database and sub-set analyses were performed.
Although no overall significant effect on woodland conversion was observed, sub-set analyses were nonetheless conducted to assess how age since transition (i.e. the age of tree stands) and woodland type (temperate deciduous, temperate coniferous, tropical, agroforestry) influence earthworm communities.
To evaluate differences in effect on pre- and post-menopausal breast cancer, we made sub-set analyses of cases with an age at diagnosis of above and below 50 years.
We excluded: studies reporting only physiological endpoints (for example, changes in immunological variables); descriptive studies; retrospective cohort studies; studies in the pediatric population; and studies exclusively reporting series of meningitis, typhoid fever and pneumonia where sub-set analyses of patients of interest (for this meta-analysis) were not reported.
We selected five alternative relationships of rhodymeniophycidan orders based on sub-data set analyses that had more than 50% of nodes supported with greater than 80% maximum-likelihood bootstrap (MLB) (supplementary fig. S2, Supplementary Material online).
All analyses that required sub-setting the data according to DS user status were performed using the domain statement.
All clones on the array are taken from a sub-set of the EST data set analysed in [ 27] (accession numbers: dbEST: 49109381 49125759, Genbank: EW744731– EW744731).
It was concluded that the varying sub-sets of patients analysed were not unrepresentative of the total pool of 784 patients.
Principal components analyses generated a similar set of four factors in both the unipolar and bipolar sample sub-sets and congruent with previous analyses undertaken in non-clinical samples, suggesting identification of normative dimensions that underpin hypomanic and manic mood states.
The sub-180 μm fraction of all samples was analysed by inductively coupled plasma mass spectrometry following aqua regia (partial) digestion for 65 elements, and by Leco CS320 element analyser for total C and S. Sub-sets of the samples were analysed by XRF for 12 oxides/elements.
