Summary of results of duration of hospital stay, recovery time, loss of working time.

<p>This table shows the results for the duration of hospital stay, recovery times, and loss of working time in five groups (Group A, Group B, Group C, Group D, Group E). “Recovery time” means the postoperative activity time. “Duration of hospital stay” means the postoperative days in hospital. “Loss of working time” represents the duration from admission to the start of work after hospital discharge<b>.</b> Data are expressed as the mean ± standard deviation.</p>★<p><i>p</i>>0.05 vs. Group A;</p>▴<p><i>p</i><0.05 vs. Group B;</p>•<p><i>p</i>>0.05 vs. Group B.</p><p>Summary of results of duration of hospital stay, recovery time, loss of working time.</p

Summary of baseline characteristics of intradural extramedullary tumor patients.

<p>There was no significant difference between the MIS group and Non-MIS group (p>0.05). This was the same among the five groups (Group A, Group B, Group C, Group D, Group E; p>0.05) and among the three groups (Group HE, Group LE, Group LESPF; p>0.05). Data are expressed as the mean ± standard deviation.</p><p>Summary of baseline characteristics of intradural extramedullary tumor patients.</p
