  1. *Compared with the left side, P < 0.01; ** Compared with females, P < 0.001
  2. LSR: Left Success Rate; RSR: Right Success Rate; BSR: the Puncture Success Values of both sides were larger than or equal to 34 for the identical vertebra), and the Either Side Success Rate (ESR: the Puncture Success Value of either side was larger than or equal to 34). The Female Success Rate (FSR) was calculated as follows: for example, if for the L1 level, a puncture was performed through both sides, then for 100 females, there were 200 punctures. If, of the 200 punctures, 84 were considered successful, then the FSR = 84/200). The Male Success Rate (MSR) is calculated as for the FSR)
