Fig. 7.

Box-and-whisker plots representing pore shape of fiber bundles produced at various core flow rates and production times. (a) Core flow rate (0.8 mL/h, 1.0 mL/h and 1.4 mL/h); (b) production time (0.5 h, 1.0 h and 2.0 h). Median values, interquartile ranges (i.q.r.) and 1.5 times the i.q.r (excluding outliers ° and extreme values *) are denoted by horizontal bars, boxes and whiskers respectively. The change in pore shape parameter was significant with the increasing core flow rate (Kruskal–Wallis, p < 0.01) but not with production time (Kruskal–Wallis, p = 0.815).
