Fig. 7

The number of successfully transferred pins across sessions for the subjects in the intervention group (boxplots) and the participant with dysmelia (black dots). The boxplots depict median (horizontal line), interquartile range (box), min and max values (whiskers), and outliers (cross). The horizontal bars indicate statistically significant difference (*, p < 0.05; ***, p < 0.001). Note that the performance consistently increased across the training sessions
