Can CT-guided cervical nerve root injections delay or prevent the need for surgical intervention in cervical radiculopathy?
Observational study in Skeletal radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo evaluate the effectiveness of computed tomography (CT)-guided cervical nerve root injections (CNRI) for cervical radiculopathy, identify predictors of favourable pain response, and assess their impact on subsequent surgical intervention rates.
methodsRetrospective observational study included 148 patients undergoing CT-guided CNRI for cervical radiculopathy between October 2021 and April 2024 at a regional neuroscience centre in the Northwest of England providing a tertiary-level specialist care. Data on demographics, clinical presentation, radiological findings, procedural details, patient-reported outcomes, and subsequent surgery were collected. Univariate and multivariate logistic regression analyses were performed to identify predictors of pain improvement.
resultsOverall, 66.2% (98/148) of patients reported improvement in radicular pain following CT-guided CNRI (55.1% substantial, 44.9% partial), with a mean symptom relief duration of 20.2 weeks (SD 22.8). Multivariate analysis identified unilateral symptoms as a significant positive predictor of improvement (OR = 7.0, 95% CI 2.01-24.08, p = 0.002), while multilevel disease (OR = 0.40, 95% CI 0.15-0.98, p = 0.047) and prior cervical surgery (0.31, 95% CI 0.11-0.82, p = 0.018) were significant negative predictors. During the study period, 24.3% (36/148) of patients proceeded to or were listed for cervical spinal surgery. No major neurovascular complications were reported.
conclusionCT-guided CNRI provides effective short- to medium-term pain relief for a majority of patients with cervical radiculopathy and can reduce the need for subsequent surgery in approximately three-quarters of cases. Treatment success is more likely in patients with unilateral symptoms and without multilevel disease or prior cervical surgery. These findings can aid in patient selection and counselling.
