      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients, using random allocation software, were randomly divided into clacitonin transforaminal epidural injection with caudal epidural injection.  By selecting the simple randomization method in the randomization box and entering the determined total sample size in this software, numbers were given to the patients and the patients were allocated into two groups according to computer-generated numbers, Blinding description: The outcome assessor and the statistical analyzer were unaware that the patient was exposed to the clacitonin transforaminal epidural injection with caudal epidural injection.  The groups are provided to the statistical analyzer in the form of codes A and B for analysis.</study_design>
