The power analysis showed that a number of 5902 participants in each group was adequate in order to detect real proportion differences greater than 0.03, achieving power 90% at a significance level of 0.05.
Taking these studies together with our own, zebra finch probes have now been shown to be adequate for detecting signals in the all three major superfamilies of the Passerida parvorder of the oscines (divergence time < 50 MYA) [ 1, 54, 55].
Although sentinel platforms in all countries may be adequate for detecting A(H7N9), their limited geographic coverage could miss cases.
For instance, Joyce and others (2008) highlight the need to monitor both native plant species and non-native species while suggesting a more general monitoring program would be adequate to detect changes in tree establishment, growth and mortality.
Anesthesia and procedure times and per operative and postoperative side effects were recorded.> Before initiating the study, a power analysis suggested that a sample size of 20 patients in each group should be adequate to detect a 30%% reduction in extubation time and agitation score with a power of 0.8 and α of 0.05.
Thus, the sample size of 745 women in the quantitative component of this paper should be adequate to detect the differences in mental health outcomes among never abused women, physically abused women, and physically abused women who have experienced sexual aggression victimization.
A sample of about 36 in each group was found to be adequate to detect a 10% change in the Oswestry Low Back Pain Disability Questionnaire assuming a between patient variability of 15% [8], [9], a two-sided significance level of 5%, and a power of 80%.
However, Donoghue et al. (1996) describes that a single exposure to a drug might be adequate to detect the drug in either egg white or yolk, depending on the characteristics of the drug and sensitivity of the analytical method applied.
In 2004 2005, we collected 6 10 female lesser scaup from each site and 25 females annually at Pool 19; previous studies indicated that these sample sizes would be adequate to detect important differences in body-condition dynamics of scaup [13], [15], [20].
These sample sizes would not be adequate to detect small variations in sex ratio.
