Distribution of knowledge scores per hospital. Sites have been arranged in order of median response per hospital. The centre line for each box plot is the median value, the upper-lower limits of the box are the 1st and 3rd quartile. The whiskers correspond to the maximum and minimum points that are 1.5* the IQR from the 1st and 3rd quartiles. Data that exceed these limits are considered outliers and plotted individually
