Box plot graph of the pattern cutting task comparing the normalised scores achieved by the 22 participants using both the glove port and the SILS™ port. The Y-axis represents the normalised scores. The boxes represent values between the first quartile (Q1) and the third quartile (Q3). Whiskers ranging from Q1 to the minimum and from Q3 to the maximum. The bold line shows the median. The first box plot on the X-axis represents the glove port and the second box plot represents the SILS™ port. The p-value indicates the significance of the difference between the two ports using the general linear model
