The fact that Mr. Trump sought out Mr. Reynolds to discuss the Twitter message and seek more proof of the size of his crowd during his first full day as president is further evidence of the anxiety that he has demonstrated when people raise questions about the extent of his public support.
For proof-of-concept, a medium-size training set (150 h) of reverberant speech was generated from 150-h high-quality clean speech convolving with real RIRs.
The proof-of-concept device approximates the size and form of a conventional prosthetic foot, but has separate rear-foot and fore-foot components that rotate about a medio-lateral axis at mid-foot.
Biomarkers complementing clinical evaluations may help to reduce the length and size of proof-of-concept (PoC) trials aimed to obtain quick "go/no go" decisions in the clinical development of new treatments.
For this proof-of-concept study, a sample size of 30 participants was estimated to be sufficient to reliably exclude an unacceptable lack of repeatability in 0- or 120-min glucose levels obtained in the home or observed settings compared with the nurse-run settings.
AR: Androgen receptor; IHC: Immunohistochemistry; CTC: Circulating tumour cells; BCTI: β-content γ-confidence tolerance intervals; K: Cohen's Kappa; CRPC: Castration-resistant prostate cancer; POM: Proof-of-mechanism; ISET: Isolation by size of epithelial tumour cells; ISR: Incurred sample reanalysis; REC: Research ethics committee.
In summary, despite the limitations of this proof-of-concept study (small sample size, short treatment duration and open-label design), IDegAsp was shown to be a promising new treatment option for initiating insulin therapy in subjects with type 2 diabetes inadequately controlled with OADs.
Apart from experiments in rodents, cyclosporine A when given at reperfusion reduced infarct size in a proof-of-concept study in patients with acute myocardial infarction [ 12].
If the pilot is a proof-of-concept study, is the sample size calculated based on primary/key surrogate marker(s)?
In developing translational studies, which bring novel medicines to patients, it will be useful to stratify patients by the likelihood of developing subsequent muscle loss and circulating miR-181a could be useful for this purpose by reducing the size of a proof-of-concept study.
