This may have two reasons: either there was really no difference in responses, or there was a difference in responses that could not be detected by the test due to the (too small) group size.
Owing to the unequal, and in some cases too small, group sizes, main effects were then confirmed by non-parametric (Mann-Whitney) tests.
Nevertheless these cases were not included in the analysis, due to too small group sample.
In order to avoid too small group sizes only data values within the interquartile range were considered as optimal cut-off.
The few individuals with religious affiliation other than Christian had the highest scores for USP and ExP, but due to a too small investigation group, this statement can be valued only as a hint.
This correlation was lost in the smallest subgroup, probably due to a too small patient number in this group.
Thus, we decided on the second boundary (500), a larger boundary would decrease the number of patients in the second group while a smaller one would result in a too small time range of the first group.
"I think Asia is still a minority, still too small a group to be commercially valuable.
Six patients treated initially at 350 mg m−2 represent too small a group to justify an extensive separate analysis, therefore results are focused on the 51 patients treated at 320 mg m−2, the majority of whom (84%) relapsed or progressed within 12 months of initial chemotherapy.
Too small a group and dominance of men do not allow for a generalization of the results.
