First a high-level theoretical method was setting up in order to compute the structures and properties of GlyH+water complexes, Gly being the simplest AA and a suitable model for such a study [3].
In such a study, 65 536 different 8-nt-long sequences, so-called words, were investigated with respect to frequency and positional distribution in the A. thaliana genome (9).
The number of patients that would be required becomes prohibitive, as does the amount of time that would be needed to perform such a study: 573 patients were recruited over 3 years in the CONTROL study [ 5].
Although this is a reasonable rate of recruitment for such a study 36 and there were no significant differences in age, parity, or ethnicity between those who did and those who did not consent, 15 there is still a possibility of selection bias in the current study population.
Reliable and valid assessment instruments are essential for such a study [ 16, 42].
Although Gross demonstrated short-term increases in nursing staff, no studies have evaluated the effect on core health services at the local level, nor the feasibility of conducting such a study [ 15, 16].
While a head-to-head randomized controlled study is generally considered the most robust method for comparing two competing interventions, this type of study data is rarely available given the time, expense, and dependency on manufacturers' incentive to conduct such a study [ 6, 7].
The edge length derived from such a study was 70 nm, together with a wall thickness of 6 nm.
We also compared the 50 women who would accept to be enrolled in a RCT on a new versus a standard drug, with the 450 who would decline participation in such a study (Table 2).
An open-ended written questionnaire item might better facilitate such a study [ 50].
A recently published prevalence study from the United Kingdom is an excellent example of such a study [ 89].
