Myocardial perfusion scintigraphy in myocardial infarction - impact of ST-segment elevation and of Diabetes mellitus.
Article in Porto biomedical journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Myocardial perfusion scintigraphy (MPS) is frequently used in the evaluation of patients with coronary artery disease, either stable or with the prior remote acute coronary syndrome. The goal of the present work was to evaluate changes in MPS according to the nature of the infarction (ST-elevation vs non-ST elevation status) as well as according to the presence or absence of Diabetes mellitus. A prospective study of 124 consecutive patients with myocardial infarction (MI) was carried out using MPS. Patients with ST-segment elevation MI (STEMI) had significantly larger values both for percentage and absolute areas of perfusion defects, both at rest and in a stress situation, when compared to patients without ST-segment elevation (NSTEMI). These patients had significantly lower values for left ventricular ejection fractions (EF), in a similar comparison. The values for perfusion defects at rest for STEMI patients were more than double the values for NSTEMI patients (17.1 ± 14.6% vs 6.5 ± 7.8%,
