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
Purpose: To report the short-term outcomes of lumbar sympathetic radiofrequency ablation (LSRA) in patients with peripheral arterial disease (PAD) who were refractory to conservative management or unsuitable for revascularization, and to generate preliminary evidence to inform the design of future prospective investigations. Patients and Methods: A retrospective, self-controlled analysis was conducted on consecutive patients with PAD who underwent LSRA at our institution between July 2025 and March 2026. Pain intensity (Faces Pain Scale-Revised, FPS-R), toe skin temperature, and perfusion index (PI) were measured preoperatively and on postoperative day 7. Complications were documented. Normality of between-condition differences was assessed using the Shapiro-Wilk test. Wilcoxon signed-rank tests were used as the primary analysis for non-normally distributed variables, with paired t-tests as sensitivity analysis. Effect sizes (Cohen's d for paired samples) with 95% confidence intervals were calculated. Results: Sixteen patients were included, comprising 14 cases of atherosclerotic occlusive disease and 2 cases of thromboangiitis obliterans. At postoperative day 7, FPS-R scores decreased from 5.88±1.36 to 3.75±1.24 (V=91, p=0.001; Hedges' g=1.48, 95% CI 0.77-2.17, large effect), toe skin temperature increased from 35.06±1.04 °C to 35.95±0.78 °C (t=-5.06, p=0.00014; Hedges' g=-1.20, 95% CI -1.82 to -0.56, large effect), and PI increased from 2.92±1.71 to 3.94±1.71 (V=0, p=0.0005; Hedges' g=-2.02, 95% CI -2.87 to -1.16, large effect). One patient (6.25%) experienced lumbar artery injury requiring embolization, with successful resolution; no other major complications were observed. Conclusion: In this preliminary, short-term, retrospective pilot study of carefully selected PAD patients, LSRA was associated with improvements in pain, toe skin temperature, and perfusion index at postoperative day 7. These findings require validation in prospective, controlled trials with longer follow-up.
