The PLAN trial: precision treatment of lumbar spine surgery with advanced nerve root blockade - protocol for a prospective, investigator-initiated, randomized non-inferiority trial.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundLumbar radiculopathy, due to nerve root compression, leads to significant pain and functional impairment. Surgical decompression is a treatment option, but not all patients achieve good outcomes. This protocol for an ongoing randomized controlled trial aims to compare the outcomes of surgical planning with a diagnostic selective nerve root block and surgical planning without a diagnostic selective nerve root block (standard of care).
methodsThe PLAN trial is a multicenter, block-randomized, controlled, non-inferiority trial that will enroll patients diagnosed with unilateral lumbar radiculopathy. Participants who have been deemed surgical candidates will be randomly assigned to one of two groups: Group A will receive standard surgical decompression, while Group B will undergo selective nerve root block to determine what nerve root is causing the patient's pain, followed by surgical decompression or conservative management. The primary outcome measure is the difference in the Numerical Rating Scale for Leg Pain from baseline to 3 months with a non-inferiority margin of 1.6 points. Secondary outcomes are the difference in proportions of patients reaching ≥ 1.6 points on the Numerical Rating Scale for Leg Pain, the difference in scores and time course on Numerical Rating Score for Leg Pain and Back Pain, Short-Form 36, EuroQol-5D-3 L, and Oswestry Disability Index. Analysis will also be performed after 1 year.
conclusionThis trial seeks to provide high-quality evidence on the effectiveness of integrating selective nerve root blocks to guide surgical decompression or avoid surgery in treating lumbar radiculopathy. The findings aim to inform clinical decision-making and optimize patient outcomes.
