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
backgroundSpinal catheter angiography is commonly performed in the evaluation and treatment of spinal vascular lesions. The typical approach to spinal angiography consists of access through the femoral artery with the use of suitably shaped catheters for selective catheterization of the spinal segmental vasculature. The purpose of our study was to evaluate the safety and feasibility of distal transradial access through the "anatomical snuffbox" for targeted spinal angiography, for the investigation and treatment of selected spinal lesions.
methodsA retrospective review of patients who underwent transradial spinal angiography and embolization was performed from August 2019 to January 2022. A total of eight patients were identified, who underwent targeted spinal angiography through distal transradial access. Outcome measures were documented in a tabular manner.
resultsRadial access was successful in all patients. Seven patients had vascular tumors of the spinal column and underwent tumor embolization followed by segmental artery occlusion prior to surgery. One patient had a spinal dural AV fistula that could not be embolized due to feeding vessel tortuosity and eventually went on to have a laminectomy. Mean fluoroscopy time was 31.4 min. There were no access site hemorrhagic complications. One patient experienced transient mild hand numbness during the period of hemostasis with the vascular compression device that resolved completely within 24 h.
conclusionsDistal transradial access is a feasible and safe option for targeted spinal angiography and treatment in selected patients.
