The effectiveness and predictive factors of Sacroiliac Joint Radiofrequency Neurotomy success - A retrospective cohort study.
Article in Interventional pain medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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: The Sacroiliac Joint (SIJ) accounts for 10-27% of lower back pain. Radiofrequency neurotomy (RFN) is commonly utilized for refractory pain. Outcomes are variable and may be related to patient selection and procedural technique differences. Objective: To assess the effectiveness and outcome success predictors of SIJ RFN at three months. Design/Methods: Data of patients undergoing SIJ RFN were extracted from the electronic medical record of one physiatrist's interventional pain practice between 2016 and 2021. The extracted data included the following outcome variables: ≥2 decrease in Numerical Rating Scale (NRS) [minimal clinically important difference MCID-2], ≥50% NRS reduction, and ≥17 points decrease in the Pain Disability and Quality of Life Questionnaire - Spine (PDQQ-S) [MCID]. Predictor variables included block type [>79% LBB/LBB, >79% IA/LBB, 50-79% LBB/LBB, 50-79% IA/LBB, >79% LBB, and 50-79% LBB] and cannula type/configuration [16 g/longitudinal, Trident bipolar/perpendicular, and 18 g quadripolar/perpendicular]. Data analysis included descriptive statistics and logistic regression with an odds ratio (OR). Covariates included in the logistic regression models were age, gender, and laterality (right, left, and bilateral). Results: Of the 128 patients analyzed for this study (20.8% males; 60.4 ± 14.4 years of age), 66.9% achieved MCID-2 in NRS, 53.9% experienced ≥50% NRS reduction, and 50% experienced ≥17 points decrease in PDQQ-S. Achieving MCID-2 in NRS for the 18 g quadripolar/perpendicular technique was approximately four times higher than the odds for 16 g/longitudinal technique (OR = 3.91; 95% CI = 1.34-11.43; Conclusion: SIJ RFN effectively reduces pain and improves function in most patients at three months. Quadripolar/perpendicular technique and younger age predict SIJ RFN treatment success, whereas block type does not.
