The role of M-mode echocardiography in patients with heart failure and preserved ejection fraction: A prospective cohort study.

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
Epicardial movement during diastole is inversely proportional to myocardial stiffness but systolic regional thickening cannot precisely identify ischemic territories. The aim of the present study was to test the hypothesis that a correlation may be present between M-mode echocardiography parameters and poor outcomes in patients with heart failure and preserved ejection fraction. Patients with known cardiovascular disease were included in the test group (n=1,244) and patients without known cardiovascular disease were included in the control group (n=1,952). Patient records of routine measurements, M-mode echocardiography and mortality were collected. The control population and test population had the same left ventricular end-diastolic dimension (P=0.062) and left ventricular end-diastolic volume (P=0.053). A lower mitral flow velocity (P<0.05), higher Tei index (P<0.0001) and reduced distribution of diastolic wall strain (P<0.0001) were reported in the test populations compared with the control population. Patients of the test population with lower diastolic wall strain (<0.28) demonstrated a higher mortality rate than those with higher diastolic wall strain (≥0.28; P<0.0001) at the 3-year follow-up. M-mode echocardiographic parameters may be of use for predicting poor outcomes in patients with heart failure and preserved ejection fraction.
