This represents a rather small sample, but not impractically so, for high resolution micro CT systems.
Besides having a rather small sample size and a short follow-up time, they were often characterized by vague and subjective assessment of disease activity and treatment response.
As experimental designs in this field are generally performed using a rather small sample of subjects, general methods described in literature are reconsidered resulting in a specialized analysis for visual perception experiments on displays.
Simulations show that the ANOVA-type statistic and the multiple contrast test appear to maintain the pre-assigned level of the test quite accurately (even for rather small sample sizes) while the Wald-type statistic leads, as expected, to somewhat liberal decisions.
However, the results should be interpreted with some caution due to the rather small sample size.
Finally, due to a rather small sample size our results need to be further validated.
This purposive sampling method aims at maximising the diversity of perceptions with a rather small sample representing different interests.
More problematic was the rather small sample size of 1137, further diminished to 573 by participation of only 50.4%.
