Left atrial function analysis in patients in sinus rhythm, normal left ventricular function and indeterminate diastolic function.

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
Assessment of diastolic function by echocardiography may be indeterminate as demonstrated in previous studies where diastolic measurement is a discrepant. We aimed to assess whether left atrial (LA) function may contribute to left ventricle filling evaluation in patients with indeterminate diastolic function (IndtDFx). This retrospective study included 3 groups of patients based on diastolic function: normal diastolic function (NDFx), definite diastolic dysfunction (DDFx) and IndtDFx. All patients had sinus rhythm with left ventricular ejection fraction ≥ 45%. Diastolic function was determined according to the following echocardiographic parameters: mitral E', mitral E/E' ratio, LA maximal volume index, and pulmonary pressure. NDFx was defined as having less than 2 abnormal parameters, DDFx as more than 2 abnormal parameters, and IndtDFx as 2 abnormal parameters. LA function analysis was performed in all patients using echocardiographic 2D speckle tracking. Sixty seven patients were included in strain analysis. The DDFx group (n = 21) and IndtDFx (n = 19) were significantly different from NDFx (27) in some demographics, cardiovascular risk factors, presentation and echocardiographic parameters. Some of the phasic LA function (phasic LA volumes and strains) parameters in the IndtDFx group were similar to DDFx and significantly different from the NDFx group, while other parameters fell in between the two groups. Phasic LA minimal volume index was found to be associated with heart failure symptoms. The IndtDFx group is a heterogeneous group demonstrating clinical and echocardiographic profiles that closely resemble that of DDFx group. LA phasic function analysis may help in re-classification of patients with IndtDFx as actual DDFx or as NDFx.
