Prognostic values of left atrial strain analyzed by four-dimensional speckle tracking echocardiography in uremia with preserved ejection fraction.

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
Little is known about the prognostic value of left atrial strain by four-dimensional speckle-tracking echocardiography in end-stage renal disease patients with preserved left ventricular ejection fraction. This prospective study collected clinical and echocardiographic data from 80 stable dialysis patients (mean age 57 ± 10 years; 62.5% men). All patients underwent the dedicated four-dimensional speckle-tracking echocardiography to measure LASr (peak longitudinal strain of reservoir function), LAScd (peak longitudinal strain of conduit function), LASct (peak longitudinal strain of contractile function), LASr_c (peak circumferential strain of reservoir function), LAScd_c (peak circumferential strain of conduit function) and LASct_c (peak circumferential strain of contractile function). These patients were enrolled from August 2021 to August 2023 and followed-up for 19 months (interquartile-range 15 to 20 months). The primary outcome was a composite of all-cause mortality or major adverse cardiovascular events (MACEs). The study patients were classified into event (developed mortality or MACEs) and event-free group according to the primary outcome. Multivariate Cox regression analysis was used to investigate risk factors for all-cause mortality or MACEs. The event group had lower LASr (16.4% vs. 21.2%, P = 0.0003), LASct (8.2% vs. 11.2%, P = 0.01), LASr_c (25.2% vs. 35.0%, P = 0.0004) and LASct_c (14.9% vs. 20.9%, P = 0.001) than the event-free group. Using optimal cut-off value determined by ROC curve, the less LASr (LASr < 18.5%), LASct (LASct < 8.5%), LASr_c (LASr_c < 28.5%), and LASct_c (LASct_c < 17.5%) group had a higher mortality or MACEs rate. Multivariate cox regression analyses revealed that LASr (HR = 0.81, 95% CI [0.17; 0.91], P = 0.0005, per 1% increase) and LASr_c (HR = 0.93, 95% CI [0.87; 0.98], P = 0.01, per 1% increase) were independent predictors of all-cause mortality or MACEs. Less peak longitudinal and circumferential strains of reservoir function are predictive of poor prognosis among end-stage renal disease patients with preserved left ventricular ejection fraction.
