Reliability of myocardial perfusion gated SPECT for the reproducible evaluation of resting left ventricular functional parameters in long-term follow-up.
Article in European journal of nuclear medicine and molecular imaging, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposePerfusion gated single photon emission computed tomography (SPECT) can assess with good reproducibility left ventricular (LV) volumes and ejection fraction (EF). Whether this reproducibility is maintained in long-term follow-up is unknown.
methodsWe compared LV end-diastolic (ED) and end-systolic (ES) volumes (V) as well as EF calculated using gated SPECT and QGS software in 103 coronary artery disease patients studied twice at > 1-year interval because of standard clinical indications. Patients were divided into two groups: (A) 67 patients without major clinical changes and with stable resting perfusion and (B) 36 with modified clinical status or resting perfusion.
resultsThe relationship between gated SPECT 2 EF (=y) and gated SPECT 1 EF (=x) was for group A: y=0.91 x + 5.34, r=0.92, p<0.0001, SEE=4 and for group B: y=0.67 x + 13.6, r=0.63, p<0.0001, SEE=10. The 95% limit of agreement was 8 EF units for group A and 20.6 EF units for group B. For EDV, the 95% limit of agreement was 22 ml for group A and 52 ml for group B. For ESV, the 95% limit of agreement was 13 ml for group A and 44 ml for group B.
conclusionIn stable patients with an unmodified resting perfusion pattern the functional parameters derived from perfusion gated SPECT have good reproducibility even after a prolonged time interval. This supports the value of gated SPECT for serial evaluations of LV function.
