Fig. 4. Linear regression analysis of surface tension versus volume for CHO-Ncad
and CHO-A5 aggregates. Aggregates of CHO-Ncad (
) ranging in volume from
0.1 to 0.3mm3 were subjected to TST. Linear regression analysis of
the data generated a correlation coefficient (r2) of 0.099,
indicating that no statistically significant correlation exists between
and volume. A similar analysis of CHO-A5 (O) aggregates produced an
r2 value of 0.402, suggesting a possible weak relationship between
and volume.
