| The Δ value represents the absolute value of the difference between preoperative score and the corresponding postoperative score at each follow-up time point. CTG – corticosteroids treatment group; NCTG – non-corticosteroids treatment group; NRS-LP – numerical rating scale for leg pain; NRS-LN – numerical rating scale for leg numbness; ODI – Oswestry Disability Index; SF-36 – Short Form Health Survey. | |||||
