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

backgroundCombined interpretation of late diastolic mitral annulus velocity (A') with left atrial volume index (LAVi) may have additional benefits in the assessment of diastolic dysfunction. HYPOTHESIS: The LAVi/A' ratio may be useful in the identifying advanced diastolic dysfunction (ADD) and predicting clinical outcomes in patients with dyspnea.

methodsWe enrolled 395 consecutive patients hospitalized with dyspnea (New York Heart Association class II-IV) and performed transthoracic Doppler echocardiography and B-type natriuretic peptide (BNP) measurement. LAVi/A' values were evaluated in terms of diagnosing ADD and predicting clinical outcome.

resultsOn the receiver operation characteristic curve analysis for the determination of ADD, the area under the curves of LAVi/A' in the entire population was comparable to those of BNP (0.94 vs 0.93, P = 0.845) and mitral E/E' (0.94 vs 0.93, P = 0.614) and higher than that of LAVi (0.94 vs 0.87; P = 0.014). A LAVi/A' of 4.0 was the best cut-off value to identify ADD. During a median follow-up of 31.9 months (range, 0.3 to 45.7 months), the group with LAVi/A' ≥4.0 had a higher incidence of primary composite outcomes (cardiac death and/or rehospitalization for heart failure) than the group with LAVi/A'<4.0 (25.0% vs 3.3%, P < 0.001). LAVi/A' ≥4.0 was an independent predictor of clinical outcomes (odds ratio, 3.245; 95% confidence interval, 1.386-7.598; P = 0.007).

conclusionsAs a new echo index, LAVi/A' is a useful parameter to identify ADD and predict clinical outcomes in patients with dyspnea.
