Congestion, but not low cardiac output, is independently associated with acute kidney injury following contrast agent exposure.

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
Aim: Contrast-associated acute kidney injury (CA-AKI) is frequently associated with adverse outcomes. Renal perfusion gradient is central to glomerular filtration. While renal vasoconstriction can partially compensate low-output-associated impairment of the renal perfusion gradient, venous congestion cannot be compensated. We hypothesized that congestion is a stronger predictor of CA-AKI than low output in cardiovascular diseases. Methods and results: An all-comer single-center cohort of 3,126 cases undergoing coronary angiography with simultaneous right heart catheterization was analyzed. Patients were divided into four categories: congested [right atrial pressure (RAP) >10 mmHg and cardiac index (CI) >=2.2 L/min/m Conclusions: Venous congestion is independently associated with CA-AKI and is a stronger predictor of CA-AKI than low cardiac output.
