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
objectiveSubclavian steal syndrome results from hemodynamic impairment due to stenosis or occlusion of subclavian artery. Therefore, it is important for subclavian steal syndrome patients to assess hemodynamic status during endovascular therapy.
methodsEleven subclavian steal syndrome patients undergoing endovascular therapy attended this study. Pressure wire was used to measure trans-stenosis pressure difference (ΔP). Digital subtraction angiography, Transcranial Doppler and Electronic sphygmomanometer were introduced to assess stenotic rate, steal grade and inter-arm systolic pressure difference, respectively. Clinical symptoms and restenosis were followed up after endovascular therapy. The associations of ΔP with stenotic rate, inter-arm pressure difference, steal degree, clinic symptoms and restenosis were analyzed in this paper.
resultsPrior to the therapy, ΔP moderately correlated with stenotic rate (r = 0.757,
conclusionThe trans-stenosis pressure difference is closely related to steal degree and clinical symptoms. The measurement of hemodynamic status by pressure wire is very useful to guide endovascular therapy in subclavian steal syndrome patients. However, the restenosis may still occur, even though the hemodynamic impairment is improved.
