Perfusion Scintigraphy for the Evaluation of Patients with Raynaud's Phenomenon.
Article in Nuclear medicine and molecular imaging, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Raynaud's phenomenon (RP) is a functional vascular disorder, which can be defined as transient vasospasm of the peripheral arteries and arterioles in the affected areas exposed to the cold or other stress. The diagnosis of RP is mainly based on symptoms. Perfusion scintigraphy, with or without cold stimulation, can be used to evaluate RP. Studies with perfusion scintigraphy for RP have shown that patients with RP showed lower finger-to-palm ratio than patients without RP. Responses after cold stimulation were also different in patients with RP. Not only decreased perfusion or blood pool after cold stimulation but also paradoxically increased perfusion can be shown in patients with RP. Some studies have shown that primary and secondary RP can be differentiated by perfusion scintigraphy. Correlation between duration of disease and findings on perfusion scintigraphy was reported. Perfusion scintigraphy can show differences before and after treatment as well. However, the protocols for perfusion scintigraphy for PR vary among studies. The standard protocol of perfusion scintigraphy for RP should be established.
