Fig. 3From: Pre-operative declining proportion of fractional anisotropy of trigeminal nerve is correlated with the outcome of micro-vascular decompression surgeryDeclining proportion of FA value was statistically significance for different vessel or outcome. a The average declining proportion of FA value of “success” and “failure” group was 0.32 ± 0.09 to 0.14 ± 0.10 (P = 0.002 < 0.05). b The declining proportion of FA value of artery (including the artery plus vein situation) was 0.34 ± 0.06 in contrast to 0.15 ± 0.08 with vein (P = 0.000 < 0.05)Back to article page
