a The von Mises stress distribution of the normal foot group. b, c Notably, the 1 ray amputation (RA) and 1-2 RA groups displayed the highest von Mises stress levels, indicating that the soft tissues surrounding the corresponding metatarsals in these groups are at a higher risk of reulceration. d-f In the 4-5 RA, 3-5 RA and 2-5 RA groups, the stress levels of the remaining non-amputated metatarsals did not show a marked increase. Each dot represents a value of von Mises stress recorded by the marked nodes. The box range of the boxplots extends from the 25% to the 75%, with the central line representing the median. The upper and lower dashed lines span from the 1.5% to the 98.5%.
