Efficacy of Selective Nerve Root Block for Different Types of Lumbar Disc Herniation: Study Protocol for a Single-Blind, Prospective Cohort Study.
Article in Journal of pain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Lumbar disc herniation (LDH) is a common cause of low back pain and radiculopathy. Selective Nerve Root Block (SNRB) has been widely used as a treatment for LDH; however, its efficacy across different types of LDH remains unclear. This study aims to evaluate the clinical efficacy of SNRB in treating various LDH subtypes, classified according to the Michigan State University (MSU) classification system, and to explore its potential as a safe and minimally invasive percutaneous treatment option. Methods: This is a single-blind, Prospective Cohort Study. A total of 200 patients diagnosed with LDH will be recruited and allocated into 10 groups (20 patients per group) based on their MSU classification (1-A, 1-B, 1-C, 2-AB, 2-A, 2-B, 2-C, 3-AB, 3-A, and 3-B). All patients will receive SNRB treatment under fluoroscopic guidance. Primary outcomes will include the Visual Analogue Scale (VAS) for pain intensity. Secondary outcomes will include the Oswestry Disability Index (ODI), health-related quality of life (Short Form-36, SF-36) and average weekly analgesic consumption. Assessments will be conducted at baseline, 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months, and 1 year post-treatment. Discussion: This study will provide high-quality evidence on the efficacy of SNRB in different LDH subtypes, classified according to the MSU system. The findings will guide clinical decision-making and promote the adoption of SNRB as a minimally invasive, safe, and effective treatment option for LDH. Trial Registration: This clinical trial is registered on the Chinese Clinical Trial Registry platform (ChiCTR) at https://www.chictr.org.cn/index.html, identifier: ChiCTR2200067212.
