Comparing ultrasound-guided intra-articular injection and medial branch block for lumbar facet joint pain: a clinical study.
Article in Diagnostic and interventional radiology (Ankara, Turkey), 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
purposeThis study aims to compare the effectiveness of ultrasound-guided intra-articular (IA) injections with medial branch nerve blocks in treating lumbar facet joint pain.
methodsThis retrospective study enrolled 94 patients clinically diagnosed with lumbar facet joint pain. Diagnostic blocks confirmed the diagnosis in 82 patients, evidenced by a pain visual analog score (VAS) reduction of at least 50% immediately following the injection. Of these, 42 were treated with ultrasound-guided IA injections (group 1), and 40 received ultrasound-guided medial branch blocks (group 2). Effective pain relief was defined as a VAS reduction of at least 50%.
resultsGroup 1 showed significantly higher pain relief rates compared with group 2 at both 1-month (54.76% versus 2.5%,
conclusionUltrasound-guided IA injection provides better pain relief compared with medial branch nerve blocks. This method serves as a viable alternative for patients, especially younger and middle-aged patients with lumbar facet pain due to sedentary lifestyles. CLINICAL SIGNIFICANCE: This study compared and analyzed the therapeutic effects of two different ultrasound intervention blockade methods on patients with lumbar facet joint pain, demonstrating that IA injection has a better pain relief effect and can be used as a pain relief method for patients who refuse radiofrequency therapy.
