Devices. 2017;11(3):031008-031008-7. doi:10.1115/1.4036650 Figure Legend: Comparison of means in the axial compression tests for test nails PR30, FD32, PR50, FD48, and PR50, with standard deviation. The asterisks (*) indicate the testing of the values for PR30 and DF32 (left) and of PR50 and FD48 (right) for significant differences, using the Mann–Whitney U test. Highly significant differences were found in both cases, at P < 0.0001.
