GP – group; C – cotton; P – polymer; All measurements are in micrometers (μm). Differences in mean and their standard deviations: using formula z = [(x1 − x2) − (μ1 − μ2)]/sqrt (σ12/n1 + σ22/n2). [] Dependant t test; [] Independant t test. Levels of significance: NS (Not-Significant)=P≥0.05; Significant=P |
