Correlations between WRA and NA varicosity distribution is dependent on anatomical region and running intensity. a, b Correlations between total WRA and the NA inter-varicosity intervals. c, d Correlations between total WRA and varicosity density along NA fibers or e, f NA fragment length. Correlation coefficients are designated by r values. Asterisks indicate statistically significant correlations (P < 0.05). Solid trend lines accompany strong and statistically significant correlations, while dotted trend lines indicate moderate correlations (r = ±0.6 or greater). N = 8 rats per group except N = 7 for the hemisphere of EEX
