Intra- and interobserver agreements for the counts of IENFs were highly significant, as verified by correlations (intraobserver reliability for paw pad skin tested on two counts each for ten randomly chosen slides: R = 0.9879, p < 0.0001; interobserver reliability for paw pad skin tested on one count by two observers for ten randomly chosen slides: R = 0.8303, p = 0.0047).
