A second look with prone SPECT myocardial perfusion imaging reduces the need for angiography in patients at low risk for cardiac death or MI.

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
backgroundCorrection for soft tissue signal attenuation can improve the diagnostic accuracy of single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI). The aim of this study was to correlate SPECT-MPI findings with clinical outcomes in patients who underwent stress imaging in the supine position, who also underwent "second look" stress imaging in the prone position.
methodsPatients without perfusion abnormalities were considered Normal (N = 270). Those with apparent supine stress perfusion abnormalities which all resolved during prone imaging formed the Normal-Prone group (N = 309). Patients with matched perfusion abnormalities during both supine and prone stress imaging were considered Abnormal (N = 169).
resultsDuring follow-up (187 ± 96 days), utilization rates for invasive coronary angiography were similar for Normal vs Normal-Prone patients (3.5% vs 3.8%; P = NS), but were significantly higher in Abnormal patients (42.4%, P < .0001). Coronary revascularization occurred in 0.78%, 0.64%, and 17.7% of Normal, Normal-Prone, and Abnormal patients, respectively (P < .001). Cardiac death or myocardial infarction occurred in 2.2%, 2.3%, and 6.3% of Normal, Normal-Prone, and Abnormal patients, respectively (P = .02).
conclusionsSecond look SPECT-MPI identifies patients at low risk for death or myocardial infarction, who infrequently require invasive coronary angiography.
