Chronic Coccygodynia and ganglion impar block: How does contrast material distribution affect treatment outcomes?
Article in Pain practice : the official journal of World Institute of Pain, 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
aimTo assess the influence of contrast material distribution patterns on treatment success in patients with chronic coccygodynia undergoing ganglion impar block (GIB).
methodsAn evaluation was conducted on 58 patients who underwent GIB from August 2021 to August 2023 at a university hospital's interventional pain management center. Numeric rating scale (NRS) scores were recorded before the procedure and at 1-month post-procedure. The patients were categorized into two groups based on treatment success, defined as at least a 50% reduction in the NRS score at 1 month.
resultsThere were no significant differences between the two groups regarding age, gender, BMI, symptom duration, comorbidities, coccyx curvature type, presence of anterior/posterior subluxation, presence of posterior spicule, type of approach, contrast distribution direction, and contrast dye level. Patients with coccygodynia experienced statistically significant benefits from GIB treatment at the 1-month follow-up (p < 0.001).
conclusionAlthough the use of contrast material in fluoroscopic procedures is the gold standard to prevent possible complications, the distribution pattern of contrast does not significantly affect the success of GIB treatment in patients with coccygodynia. Further prospective and long-term follow-up studies are required to validate these findings.
