Similarly, by initially fixing the power to 0.5, the sample size (per study) must be n = 420 and the corresponding TRP will be 0.60 after two studies (0.95 after three studies).
These relatively large bins cause some accuracy loss, but the use of 3D TOF sinograms has also advantages: it results in a fixed storage size per study and is the basis format for advanced rebinning techniques (like Fourier rebinning (FORE)).
Although most of the studies reported more than one effect size, for example, Kong (2007) and Guven (2012), who also reported on students' change of attitude toward computers, this study focused only on student achievement, thus reporting one effect size per study.
On average, each study had a sample size of 311 manuscripts; the average sample size per study ranged between 28 and 1983 manuscripts (some studies were based on more than one sample).
The average sample size per study was 18.8 ± 9.4 patients and 16.9 ± 8.92 controls.
For a certain outcome, only one effect size per study was included.

The current evidence of efficacy is based on relatively small sample sizes per study – with the exception of Ruiter et al. (2015) – and only one to three training sessions per condition.
In addition, although the effectiveness of the programme has been established in other countries, the effect size varied per study ranging from 0.06 to 2.76 [ 26].
Table 2 displays the SRM, ES, MDD, and sample size requirements per study arm that are sufficient to detect a change score of 2.5 units on a 0 to 100 scale.
3. Information of study designation such as: sample size per group, study design, randomization scheme, inclusion criteria, and type of end point used.
For between-instrument comparisons, we computed sample sizes required per study arm for 80% power, with an alpha of 0.05, given the delta that was observed.
