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
The purpose of this investigation was to evaluate the influence of hypertension on left atrial (LA) function in patients with moderate and severe AS. This cross-sectional study included 121 patients with moderate and severe AS and preserved left ventricular (LV) ejection fraction ( > 50%) and 79 age-matched controls who underwent a comprehensive echocardiographic examination. LA phasic function was determined by both volumetric and strain methods. Our findings showed that the LV ejection fraction was similar between hypertensive and normotensive AS patients. Maximal, minimal, and pre-A LA volume indexes gradually increased from controls to moderate-to-severe AS patients. The total, passive and active LA emptying fraction (EF) gradually decreased in the same direction. LA phasic function estimated with strain analysis showed that reservoir, conduit, and pump LA phasic functions were lower in all AS patients than in normotensive controls. However, there was no significant difference between moderate and severe AS except in LA pump function, which was lower in severe AS. Differences in LA phasic function were more prominent in volumetric than in strain analyses. Blood pressure, LV mass index, and AS severity were independent of other clinical and echocardiographic parameters associated with LA phasic function in patients with AS. In conclusion, hypertension has an additive impact on LA phasic function in patients with moderate and severe AS. Blood pressure and AS severity were independently associated with LA phasic function parameters in AS patients. Volumetric assessment of LA phasic function should not be completely replaced with strain analysis.
