Prognosis of normal stress-only gated-SPECT myocardial perfusion imaging: a single center study.
Article in The international journal of cardiovascular imaging, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
It has been advocated that using the stress followed by rest protocol, if the stress images were normal there is no need of rest images, reducing radiation exposure and costs. Our purpose was to assess the prognosis of a group of patients with normal stress-only gated-SPECT myocardial perfusion imaging. This was retrospective study that includes 790 patients with normal myocardial stress only perfusion gated SPECT images. Images were considered as normal if a homogeneous myocardial distribution of the tracer was associated with a normal ejection fraction. The mean follow-up was of 42.8 ± 13.3 months. The considered events were death of all causes, myocardial infarction and myocardial revascularization. During this period there were 85 events (10.8 %), including 57 deaths of all causes (67.1 %), 9 myocardial infarctions (10.6 %), 19 revascularizations (2.4 %). In the first year of follow-up there were 32 events (4.0 %) and excluding non cardiac deaths there were 8 events (1.0 %). Using Cox survival analysis, diabetes (HR = 2.2; CI = 1.4-3.4; p ≤ 0.0005), the history of coronary artery disease (CAD) (HR = 2.1; CI = 1.3-3.2; p ≤ 0.001), age (HR = 1.0; CI = 1.0-1.0; p ≤ 0.05) and type of stress protocol were related with events (exercise test vs. adenosine) (Exercise test: HR = 0.5; CI = 0.3-0.8; p ≤ 0.01). In a multivariate analysis the independent predictors were diabetes, CAD and the type of stress protocol. Based on these results, normal stress-only images are associated with an excellent prognosis even in patients at higher risk, diabetics and patients with known CAD.
