Heterogeneity and subgroup analyses in Cochrane Consumers and Communication Review Group reviews: Planning the analysis at protocol stage Heterogeneity
Clinical heterogeneity refers to differences associated with the participants, interventions or outcomes. Even though a review deliberately selects studies that may be similar in many ways based on these factors, there can still be substantial differences that mean it might not make sense to pool studies. For example, thinking through clinical heterogeneity might involve considering whether s...
متن کاملHow useful are systematic reviews for informing palliative care practice? Survey of 25 Cochrane systematic reviews
BACKGROUND In contemporary medical research, randomised controlled trials are seen as the gold standard for establishing treatment effects where it is ethical and practical to conduct them. In palliative care such trials are often impractical, unethical, or extremely difficult, with multiple methodological problems. We review the utility of Cochrane reviews in informing palliative care practice...
متن کاملKnot Groups That Are Not Subgroup Separable
This paper answers a question of Burns, Karrass and Solitar by giving examples of knot and link groups which are not subgroup-separable. For instance, it is shown that the fundamental group of the square knot complement is not subgroup separable. Let L denote the fundamental group of the link consisting of a chain of 4 circles. It is shown that L is not subgroup separable. Furthermore, it is sh...
متن کاملHidden Subgroup States Are Almost Orthogonal
It is well known that quantum computers can eeciently nd a hidden subgroup H of a nite Abelian group G. This implies that after only a polynomial (in log jGj) number of calls to the oracle function, the states corresponding to diierent candidate subgroups have exponentially small inner product. We show that this is true for noncom-mutative groups also. We present a quantum algorithm which ident...
متن کاملSubgroup analyses in Orgalutran trials.
I read with interest the European–Middle East Orgalutran trial (The European Orgalutran Study Group et al., 2000) and I noticed that the study extensively monitored hormonal assays (LH, FSH, oestradiol). It is well known that sufficient stimulation of both theca cells and granulosa cells by LH and FSH is required for adequate oestradiol biosynthesis (Short, 1962; Schoot et al., 1992) and hence ...
