Data are presented for variance, skewness, kurtosis, and ranges of the individual distributions, as well as the quartiles and the interquartile difference (IQ Diff.). Results from the Kruskal-Wallis test indicate that there are significant differences across the different distributions (P < 0.001). P denotes treatment with phentolamine; T denotes treatment with TEMPOL, SQ denotes treatment with SQ-29548; LN denotes treatment with l-NAME, with combinations representing treatment with multiple agents.
