Quantitative evaluation of upper extremity strength recovery after cervical epidural block: a retrospective study.
Article in Journal of Yeungnam medical science, 2025. 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
backgroundWe aimed to evaluate the clinical efficacy of cervical epidural block (CEB) in enhancing upper extremity (UE) muscle strength in patients with cervical disc herniation (CDH).
methodsTen patients with CDH underwent a single CEB session. Follow-up assessments were conducted weekly for 2 weeks through outpatient visits. Handgrip strength on the affected side (AHGS) and the interlateral difference in handgrip strength (DHGS) between the affected and unaffected sides were measured using a dynamometer before, immediately after, 1 and 2 weeks after CEB. Neck pain and radiating UE pain were assessed using a visual analog scale (VAS) at baseline and 2 weeks posttreatment.
resultsThe median patient age was 46.4 years (range, 35-78 years). The affected disc levels were C5-6 in five patients, C6-7 in three, and C5-6-7 in two. The left side was affected in six patients and the right in four. The mean VAS score for neck pain decreased from 7.2 to 2.9, whereas that for radiating UE pain decreased from 6.3 to 2.8 after treatment. Both the AHGS and DHGS improved significantly compared to the baseline values at all posttreatment times. However, no significant differences were observed among the posttreatment time points. These findings remained consistent even after adjusting for age and sex.
conclusionCEB may offer therapeutic benefits by alleviating pain and improving UE muscle weakness in patients with CDH. However, further large-scale prospective studies are required to validate these preliminary results and determine the long-term efficacy of CEB in managing CDH.
