Figure 1

Effects of a 1-day GA²LEN training program on urticaria on the level of knowledge of general practitioners in Saudi-Arabia assessed by comparing the mean number of questions answered correctly before and after the training program. The thick middle line of each box-and-whisker plot represents the median score on that scale. The ends of each box represent scores of the 25th and 75th quartiles. The whisker ends represent the scores of the 10th and 90th percentiles. *** = P < 0.001.
