Out of a total of 2020 questionnaires sent out, 2013 were returned and 13 questionnaires were not usable yielding a usable number of 2000 questionnaires.
An alternative approach to conveying the impact of COPD, as reflected in CAT scores, is to present a usable number of selected SGRQ items in an ascending hierarchy of severity or ladder.
As there is little guidance in the literature and these analyses have never been attempted in this manner we selected 10 clusters as a trade-off between inter- and intra-cluster distance and a usable number of patient states for analysis.
In all, 1008 employees answered the questionnaire, an estimated response rate of 40% (calculated by dividing the number of usable responses by the number of employees at the departments).
First, harmonization increases the quantity of usable data and numbers of biospecimens to achieve levels of statistical power necessary to detect effects underlying complex disease etiology.
The measurement of CD127 in addition with CD4 and CD25 thus allows for a rapid (below 30 minutes) and standardizable estimation of Treg numbers, usable in multicentered clinical studies.
The response rate was calculated as the number of usable questionnaires divided by the number of individuals approached.
The number of usable subject pairs n u, the number of concordant subject pairs n c and the number of tied subject pairs n t are: (6) n u = ∑ i ∑ j I y i < y j n c = ∑ i ∑ j I y i < y j and y ^ i < y ^ j n t = ∑ i ∑ j I y i < y j and y ^ i = y ^ j For time-to-event outcomes y, pairs of subjects are usable if their survival times are not equal and at least the smallest survival time is uncensored.

Whirlscape had always designed their keyboard to be usable on any number of connected devices, including wearables, the founders told me in the past.
