P1 = p-value obtained for the difference between the median variable values between the infiltrative and nodular subtypes. A two tailed Mann-Whitney test was used with a 95% confidence interval

P2 = p-value obtained for the difference between the median variable values between the infiltrative and superficial subtypes. A two tailed Mann-Whitney test was used with a 95% confidence interval

P3 = p-value obtained for the difference between the median variable values between the nodular and superficial subtypes. A two tailed Mann-Whitney test was used with a 95% confidence interval

IQR = interquartile range
