(left) Logarithmic box and whisker plot of strain (median = heavy black line, box = 1st – 3rd interquartile range, Tukey’s whiskers = 150% of the interquartile range above and below the 75th and the 25th percentiles, respectively, and dots = outliers) for Macintosh (Mac) and Miller blades. Alcohol protective pad (APP). Pairwise p’s (by MannWhitney U test): Mac v. Mac with APP (p = .877), Mac v. Miller (p = .280), Mac v. Miller with APP (p = .077); Mac with APP v Miller (p = .251), Mac with APP v, Miller with APP (p = .054), and Miller v. Miller with APP (p = .429). (center) Logarithmic box and whisker plot of strain rate (median = heavy black line, box = 1st – 3rd interquartile range, Tukey’s whiskers = 150% of the interquartile range above and below the 75th and the 25th percentiles, respectively, and dots = outliers) for Macintosh (Mac) and Miller blades. Alcohol protective pad (APP). Pairwise p’s (by MannWhitney U test): Mac v. Mac with APP (p = .001), Mac v. Miller (p = .086), Mac v. Miller with APP (p < .001); Mac with APP v Miller (p = .144), Mac with APP v, Miller with APP (p = .245), and Miller v. Miller with APP (p = .009). (right) Logarithmic box and whisker plot of strain time integral (median = heavy black line, box = 1st – 3rd interquartile range, Tukey’s whiskers = 150% of the interquartile range above and below the 75th and the 25th percentiles, respectively, and dots = outliers) for Macintosh (Mac) and Miller blades. Alcohol protective pad (APP). Pairwise p’s (by MannWhitney U test): Mac v. Mac with APP (p = .110), Mac v. Miller (p = .898), Mac v. Miller with APP (p = .988); Mac with APP v Miller (p = .179), Mac with APP v, Miller with APP (p = .100), and Miller v. Miller with APP (p = .880)
