Inflammation and hypoalbuminemia mediate the association between CKD and contrast-associated AKI.

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
objectiveChronic kidney disease (CKD) is associated with an increased risk of contrast-associated acute kidney injury (CA-AKI), but the pathways underlying this relationship, including the contribution of intermediate factors, are not well characterized. We investigated the association between CKD and CA-AKI in patients undergoing coronary angiography or percutaneous coronary intervention and evaluated the potential mediating roles of serum albumin and high-sensitivity C-reactive protein (hsCRP) in this association.
methodsDuring the study period, a total of 13,024 patients underwent coronary angiography of these, 3740 met the predefined inclusion criteria and formed the final study cohort. Multivariable logistic regression and formal mediation analyses were subsequently employed to evaluate the associations of interest.
resultsAmong the 3740 patients, 414 (11.1%) developed CA-AKI. Lower pre-procedural serum albumin and higher log-transformed hsCRP (LnhsCRP) were independently associated with increased CA-AKI risk (OR [95% CI] 0.730 [0.583-0.913], P = 0.006, and 1.385 [1.215-1.579], P < 0.001, respectively). The initial association between CKD and CA-AKI (OR 1.906 [1.552-2.342]) was attenuated after adjustment for albumin and hsCRP (OR 1.253 [0.975-1.609]). Subsequent mediation analysis indicated that serum albumin and hsCRP statistically accounted for approximately 31.3% and 56.6% of the attenuation in the association between CKD and CA-AKI, with an additional co-mediation effect of 12.1%.
conclusionsSystemic inflammation and hypoalbuminemia, beyond reduced kidney function, may help explain CA-AKI risk in CKD and could inform risk stratification strategies using inflammatory and nutritional biomarkers.
