Superscripts by injury probability (SE) values indicate statistical comparisons between body parts for the column of interest. Body parts that differed significantly (p < .05) in injury probability are denoted by different letters; body parts where the probability of injury did not differ significantly (p > .05) are indicated by the same letter. The letter sequence is from highest to lowest least-square means
