Table 4 The p-value of PM scores of nerve roots

Test value	Left(positive and negative ^a)	Right(positive and negative^a)
p-value	0.000^b	0.000^b

PM paraspinal mapping; ^aPM scores = 1,one level, one side; ^bbecause equal variances were not assumed, Satterthwaite separate variance estimation t-test was selected
