Ultrasound-Guided vs. Blind Coccygeal Corticosteroid Injections for Chronic Coccydynia: A Randomized, Clinical Trial.
Article in The archives of bone and joint surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background: Corticosteroid injection is frequently used for chronic coccydynia management. Ultrasonography can be used to improve the accuracy of the injection. This study aims to assess the clinical outcome of ultrasound-guided compared to blind coccygeal injection in chronic coccydynia. Methods: Thirty patients with chronic coccydynia were randomized into two groups and received a coccygeal corticosteroid injection at maximum tenderness point: 15 patients with and 15 patients without ultrasound guidance. The patient's pain was evaluated with the visual analog scale (VAS) at 1-, 4-, 8-, and 24-week postinjection. Furthermore, the Dallas Pain Questionnaire was assessed before injection; also, four and eight weeks after treatment. The quality of life of patients was evaluated before an assessment and four weeks after the intervention by the SF-36 questionnaire. Results: The VAS score decreased significantly 24-week after the intervention in both ultrasound-guided and blinded groups ( Conclusion: There were no significant differences in the clinical outcome of coccygeal ultrasound-guided vs. blind steroid injection for chronic coccydynia.
