The table shows the time of incubation (*t*), the average number of GUVs per micrograph of the test and of the control suspensions
(*N*_{test} and *N*_{control}, respectively) with their standard deviations (SD), the number of harvested micrographs
of the test and of the control suspensions (*M*_{test} and *M*_{control}, respectively), the difference between the number of GUVs in the test and in the
control suspensions, the statistical significance (*p* value) of the t-test subject to the difference between the test and the control suspensions,
and the corresponding statistical power *P* at α = 0,05. Asterisks denote that the difference is statistically significant and
of sufficient power.
