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
backgroundLeft ventricular diastolic dysfunction is frequently observed in patients with chronic kidney disease. Nevertheless, the relationship between chronic kidney disease and left ventricular diastolic dysfunction over time is poorly understood. This study aims to assess whether the association between chronic kidney disease and left ventricular diastolic dysfunction varies over time.
methodsWe included outpatients from the Utrecht Patient-Oriented Database, who underwent at least 2 echocardiographic assessments and had a measurement of kidney function. Linear mixed-effects models were used to estimate the associations of estimated glomerular filtration rate (eGFR) and echocardiographic parameters.
resultsA total of 1812 patients were included and stratified into 3 groups on the basis of eGFR: >90 (491), 60-90 (923), and <60 (398). The mean age was 66.7 years, with 62.3% being men. At baseline, patients with lower eGFR exhibited a higher prevalence of hypertension (62.3% versus 55.2%) and diabetes (19.6% versus 11.6%). Linear mixed-effects models showed that declining eGFR was significantly associated with increased E/e' ratio, left atrial volume index, tricuspid regurgitation velocity, and left ventricular mass index, with respective estimates of -0.03 (
conclusionsThis study shows that lower kidney function was consistently associated with a more adverse diastolic echocardiographic phenotype, characterized by higher filling pressures, greater structural remodeling, and increased hemodynamic burden. This phenotype was already established at initial clinical assessment and did not show measurable further divergence on serial routine echocardiograms.
