Diastolic dysfunction and the risk of end-stage kidney disease among patients with non-dialysis-dependent chronic kidney disease.

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
purposeLeft ventricular diastolic dysfunction (LVDD) is common in chronic kidney disease (CKD) and is suggested to be linked to worse renal prognosis. We investigated the associations between both the ratio of early mitral inflow velocity to early diastolic tissue velocity (E/e') and LVDD grades with the risk of end-stage kidney disease (ESKD).
methodsThis prospective cohort study included individuals with non-dialysis-dependent CKD from the nephrology outpatient clinics at Rigshospitalet and Herlev-Gentofte hospital, Copenhagen. All participants underwent a thorough, protocolized echocardiographic examination. The outcome was time to ESKD (defined as dialysis treatment or kidney transplantation).
resultsA total of 731 participants were included. Mean age was 57 ± 13 years and 39% were female. During a median follow-up of 3.8 years (IQR: 3.3;4.5), 102 individuals reached ESKD. In multivariable Cox regression models, both increasing continuous E/e' (HR = 1.09 [95%CI:1.03;1.15], P = 0.004, per 1 unit increase) and E/e' > 14 (HR = 3.44 [95%CI:1.44;8.26], P = 0.005) (reference E/e' < 8) were associated with ESKD, while E/e' 8-14 was not. Compared with no or indeterminate LVDD, LVDD grades 2 or 3 were associated with ESKD (HR = 2.92 [95% CI:1.44;5.94], P = 0.003), while LVDD grade 1 was not. E/e' > 14 and LVDD grade 2 or 3 demonstrated similar predictive accuracy with excellent specificity and negative predictive values, but poor positive predictive values and sensitivity.
conclusionProminent LVDD assessed by E/e' and LVDD grades was independently associated with worse renal prognosis and had similar predictive accuracy in patients with non-dialysis dependent CKD.
