Correlation between Breslow depth , presence of ulceration and tumor regression in thin melanoma. (A) Presence or absence of ulceration was correlated to Breslow depth by Mann-Whitney U test. (B) Presence or absence of regression at 10% cut off of extension was correlated to Breslow depth by Mann-Whitney U test. On each box, the central mark is the median, the edges of the box are the 25^th and 75^th percentiles, the whiskers extend to the most extreme data points note considered outliers, and outliers are plotted individually. p was considered significant if < 0.05.
