In brief, the sample size was calibrated to develop and validate a risk-stratification system to predict 7-day all-cause mortality.
9 In brief, a sample size of 130 women in each group was required to detect a 5% reduction in maternal total cholesterol and a change of 15% (about 0.22 mmol/l) in neonatal total cholesterol levels between the two groups, (α = 0.05; β = 0.20) in the intervention versus the control groups.
Due to the low numbers of clinicians who have done brief skills training, the sample size was small for some of the disciplines.
24 In brief, we determined a sample size of 1560 people with standard procedures (α error of 5%, β error of 20%, and 20% losses for independent samples); our final sample included 1307 individuals.
The survey was administered to high proportions of the target groups during the company safety briefing programme and achieved a sample size of almost 4000 respondents at an overall response rate of 83%.
However, these results should be treated with caution, because of the limited sample size and the brief time period of this pilot study.
Despite the relatively brief period surveyed (four months) and modest sample size, we still found significant effects of one measure of genetic diversity on "everyday health" in our student sample.
In brief, allowing for a 10%% dropout rate, a sample size of 200 subjects would yield 80%% power to detect a true preference proportion as low as 61%%.
As there has been no study that included a brief ACT for smoking cessation in HK, the sample size estimation was taken reference from available ACT studies for smoking cessation [ 17- 20].
In brief, studies varied considerably in their exclusion criteria, sample size, population, country location, demographic composition and HIV-specific features, such as years since diagnosis, CD4 cell count, viral load, and proportion receiving cART or with AIDS.
