This is known as the '1-10-60' rule: you should aim to detect an intrusion in no more than one minute, investigate it fully in less than ten minutes and remediate it in less than an hour.
They report that the effect size for psychological outcomes is more predictable with a median and mean of 0.38 and 0.35 respectively, therefore we will aim to detect an effect size of 0.4.
For power calculations, we assumed a common baseline rate of 12% of homes having no specified hazards for falls or for ingestions, and aimed to detect an intervention effect of at least doubling of the proportion of safe homes.
We aimed to detect an effect size of 0.8, allowing for 20% dropouts, based on the assumption of two groups of equal size and a two tailed significance threshold alpha of 0.05.
We aimed to detect an LDL-C change of 10 mg/dL to test the first hypothesis that patients randomized to receive GRS would have lower LDL-C levels than patients randomized to CRS alone.
For example, with just 15 clusters available per arm and an ICC of 0.05, power achievable for a trial aiming to detect an increase in percentage change from 40%to50%0% is limited to about 62%, irrespective of how large the clusters are made.
However, the study had initially aimed to detect an increase in PA of 25 or greater MET hours in patients diagnosed with cancer at colonoscopy compared with patients with no cancer, and samples of 46 patients with cancer and 46 patients with no cancer would have been required.
For the second hypothesis which will test whether high GRS participants would have lower LDL-C levels that those with low/average GRS and those randomized to receive CRS alone, we aimed to detect an LDL-C change of 15 mg/dL.
Some antibodies aim to detect a particular species while others are pan-malarial, aiming to detect all types of Plasmodium.Table Table 1 lists the main types of RDT that were available in 2010.
The most important system, in the Aleutians, has not been tested for its new role, and, because of the way it is positioned, it would not be able to detect a North Korean launch aimed at Hawaii.
The study will aim to detect a signal in improved overall survival that would be used to design a phase III study to definitely compare survival outcomes between the two groups.
