Moreover, the sample size (20 patients) has been judged to be adequate based on the suggestions of the entropy-based approach to sample size in translational clinical trials (Piantadosi, 2005).
His firm's processes were adequate based on the known threats, but have now been tightened, he said.
The response rate of 67% was adequate, based on our previous experiences with questionnaires.
Reliability coefficients were adequate based on the current data (α = 0.65-0.82) and test-retest reliability (intraclass correlation coefficient 0.76) [ 25].
Rather, reliability estimates were inferred to be adequate based on data from the parent-instrument (the SF-36, Barthel Index, MMSE, etc) and on the expected stability of the attributes being measured by the PBSI (assuming no change in HRQL).
As the subsequent statistical analysis yielded positive correlations, a validation study was then performed using an additional 53 patients, a power analysis was performed to ensure that this number was adequate based on the associations observed in the exploratory study.
A sample size of 360 was calculated to be adequate, based on a margin of error of 5%, a confidence level of 95% and a response distribution of 50%[ 17].
When an EAR is not able to be set an AI, which is the average daily nutrient intake level that is assumed to be adequate, based on observed or experimentally determined nutrient intake estimates by a group of apparently healthy people, is used instead [ 31].
A target sample size of 210 was determined to be adequate based on a power analysis incorporating the effect size for change in HbA1c observed in an uncontrolled pilot trial of the Project Dulce intervention (14, 15) and targeting a power of at least 0.90 with up to 30% attrition and a type 1 error rate of 5%.
Although the basic knowledge of most pharmacists was adequate, based on the responses to the questionnaire, there seems to be a lack of knowledge in several areas, which may hamper pharmacists in improving the quality of care when giving advice to physicians and preventing or correcting mistakes if necessary.
