CT-guided sacroiliac joint injection for chronic sacroiliitis: outcomes and predictors in a retrospective cohort study.
Article in La Radiologia medica, 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
purposeTo evaluate the safety, technical success, and clinical outcomes of CT-guided sacroiliac joint (SIJ) injections in patients with chronic sacroiliitis and to assess the impact of disease etiology, age, and body mass index (BMI) on therapeutic response. MATERIALS AND
methodsThis retrospective study included 80 patients with clinically and radiologically confirmed sacroiliitis who underwent CT-guided intra-articular SIJ injection between February 2020 and May 2022. Pain and disability were assessed using the Numerical Rating Scale (NRS) and the Oswestry Disability Index (ODI) at baseline and at 1-week, 1-month, and 6-month follow-up intervals. Patients were stratified by etiology (inflammatory vs degenerative), age, and BMI.
resultsAll procedures were technically successful and complication-free. Mean NRS scores improved from 6.86 ± 1.20 at baseline to 2.26 ± 0.78 at 6 months (p < 0.001). ODI scores decreased from 37.28 ± 9.84 to 5.68 ± 2.49 (p < 0.001). Greater ODI improvement was observed in inflammatory cases compared to degenerative ones (p < 0.05), though both subgroups showed significant clinical benefit. Age and BMI did not significantly affect outcomes.
conclusionCT-guided SIJ injection is a safe and effective intervention for sacroiliitis, yielding sustained pain relief and functional improvement across both inflammatory and degenerative etiologies, independent of age and BMI.
