1 · What the graph read from it

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.

2 · The registry

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

Background: The aim of this study was to assess the prognostic value of abnormal coronary computed tomography angiography (CCTA) in patients with normal single-photon emission computed tomography (SPECT) study. Methods: We retrospectively enrolled patients with normal SPECT scans and abnormal CCTA studies, who were categorized according to CCTA findings into obstructive with ≥50 %, and non-obstructive CAD <50 % coronary artery stenosis. Major adverse cardiac events (MACE) was defined as cardiovascular death and non-fatal myocardial infarction. Results: Among 1558 eligible patients, there were 1356 (87.1 %) patients with non-obstructive CAD and 202 (12.9 %) patients with obstructive CAD. Over a median follow-up of 10.4 ± 5.1 years, a total of 87 MACEs were reported. Patients with obstructive CAD were older (67.4 ± 8 vs. 60.3 ± 10 years, Conclusion: Obstructive CAD on CCTA is associated with significantly higher long-term risk of MACE in comparison to non-obstructive CAD in patients with normal SPECT.
