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

With the introduction of high-sensitivity troponin (hsTNI) assays, the clinical significance unstable angina (UA) has become uncertain. We hypothesized that impaired left ventricular (LV) two-dimensional speckle-tracking echocardiography (2D-STE)-derived peak global longitudinal strain (GLS) was able to exclude the presence of significant coronary artery disease (CAD) in UA patients without prior cardiovascular (CV) events and with a normal LV ejection fraction (LVEF). From a cohort of 200 patients admitted with UA, we selected 61 patients without prior CV events and with a normal LVEF; of these, 48 (79%) underwent invasive coronary angiography (ICA) and 24 (39%) had at least ≥ 1 significant stenosis. 2D-STE LV GLS analysis was performed offline using a dedicated automated software program. The mean patient age was 61 ± 12 years and 66% were male. Among the 48 patients selected to undergo ICA, those without significant CAD had a better 2D-STE GLS (- 19.4 vs. - 15.9%, P < 0.001). A cutoff of - 17.5% had a sensitivity of 87% and a specificity of 82% for differentiating UA patients without significant stenosis (AUC 0.86, P < 0.001). Patients who did not undergo ICA had a better GLS (- 20.2 vs. - 17.7%, P = 0.017). 2D-STE GLS had a significantly better discriminative power compared with LVEF (P < 0.001) and the GRACE score (P < 0.001) for identifying patients with significant CAD. Impaired values of 2D-STE LV GLS were significantly associated with the presence of CAD in hsTnI-negative UA patients and demonstrated better discriminative power than LVEF and the GRACE score.
