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
backgroundThe mitral annulus (MA) plays a significant role in promoting left atrial and left ventricular (LV) filling and emptying, which is dependent on LV functional properties. The present study aimed to investigate the relationship between LV strains, quantitative features of longitudinal contractility and MA size and function in healthy subjects.
methodsThe present study comprised 295 healthy adults; 117 subjects were excluded due to inferior image quality (40%). Finally, 178 healthy adults (mean age: 32.0±11.3 years, 92 males). Complete two-dimensional Doppler echocardiography and three-dimensional speckle-tracking echocardiography were performed in all cases.
resultsThe global and mean segmental left ventricular longitudinal strain (LV-LS) proved to be -16.1%±2.5% and -16.9%±2.4%, respectively. In the present study, LV-LS ≤-13% was considered to be reduced. In ROC analysis, the cut-off value for MA fractional area change (MAFAC) to predict impaired LV-LS was ≤44%, with 67% sensitivity and 69% specificity and ROC area under curve 0.73 (P=0.0005). Significantly increased LV volumes and LV mass and reduced MAFAC could be demonstrated in healthy subjects with global LV-LS ≤-13%. Significantly larger ratio of subjects with global LV-LS ≤-13% had MAFAC ≤44% (31%
conclusionsThere is a strong relationship between MA and LV longitudinal function. MA fractional area change predicts global LV-LS.
