Recommendation: Grade B Level of evidence: Moderate 1) Meta-analysis (1) In patients with LDH, surgical treatment significantly reduced leg pain (visual analogue scale [VAS] leg) at 6 months postsurgery compared with conservative treatment (mean difference=-2.40; 95% confidence interval [CI], -4.58 to -0.22; p=0.03); however, after 2 years, surgical treatment showed a favorable trend; nevertheless, the difference was not statistically significant (mean difference=-0.95; 95% CI, -3.47 to 1.56; p=0.46), indicating it did not significantly differ from conservative treatment ( Fig. 1A ).
