However, as previously mentioned, subgroups have been identified within presumably homogeneous or highly admixed populations, suggesting that a subset of individuals share some ancestry.
For this reason Bergström and co-workers used the shorter MPI-S in their cluster analysis, confirming the previously mentioned subgroups: AC, ID, DYS.
For 12 of these 28 randomised controlled trials, the authors mentioned a separate analysis plan in the publication or the protocol without mentioning subgroup analyses.
Several Bcl-2 homology domain (BH -containing proteins that do not readily fit into either of the aBH -containing three subgrouproteinsbeen described, buthateir involvement in the Bcl-2-regulatedoapoptotic pathway is oftenotontreadilyal.
Only 2.4% of publications that mentioned a subgroup analysis reported a corresponding power calculation.
There were no differences in the number of patients enrolled into the subgroups based on the diagnosed arrhythmias, except for the subgroups mentioned in the Methods section paroxysmal and long-standing persistent AFib and AFL/AT (Table 1 ).
However, in subgroup analyses of all subgroups mentioned (emergency physician-performed US, consecutively sampled patients, and using a linear probe), the confidence intervals were significant.
During the screening of conference abstracts, only studies which specifically mentioned randomization and which reported extractable outcome data (or baseline or subgroup data) were included.
Subgroups mentioned in the abstracts were classified under the subheadings phenotypes, structural and symptomatic stage, co-morbidity, and patient characteristics.
Of the journal publications stating that at least one subgroup analysis was preplanned, a third failed to mention any subgroup analysis in the corresponding protocol.
