To identify randomized controlled trials of antimuscarinics versus placebo (Figure S2), we started with the recent Cochrane review by Nabi et al. [10] and a literature search update from June 2005 to November 2007 kindly provided by the Cochrane Incontinence Review Group according to their previously published search strategy [10].
For the theme "clinical study", we used a previously published search strategy.
A previously published search filter was used (sensitivity 97.4%; precision 4.4%) (Additional file 2) [ 17].
The results have been combined with previously published searches at root(s) = 8 TeV, in decay modes to two photons and two b quarks, as well as to four b quarks, which also show no evidence for a signal.
We used a previously published electronic search strategy (box 2) to identify reports of cluster randomised trials in health research, published in English language journals from 2000 to 2008.
Similarly to previously published results, searches of available genomic and EST data failed to identify any novel members of the relaxin-like peptide family [ 28].
In order to compare our results with previously published series, we searched Medline using the search strings GERM CELL TUMOUR, GERM, TERATOMA, INFERTILITY, FERTILITY, CHEMOTHERAPY, AZOOSPERMIA, and CANCER.
In a selected subset of young patients, whole genome SNP array analysis was performed on formalin-fixed, paraffin-embedded (FFPE) tumor tissue and compared with previously published data to search for recurrent chromosomal aberrations involved in MLH1 methylation.
Studies before 2006 were identified from a previously published systematic review (searching 1995 2006) with similar but broader inclusion criteria (including non-randomised controlled trials (RCTs)).
Functional annotation was based on previously published literature, BLAST searches of non-redundant databases, and interrogation of the BAGEL3 [ 55] and BACTIBASE databases [ 56].Sequence and annotation files for blp cassette prototypes are found in Additional file 9.
The search strategy has been previously published [ 12], which includes search terms involving a combination of free-text and thesaurus terms relevant to COPD, indacaterol, salmeterol, formoterol, tiotropium, and RCTs.
