Association of Endothelial Cell Activation with Acute Kidney Injury during Coronary Angiography and the Influence of Recombinant Human C1 Inhibitor-A Secondary Analysis of a Randomized, Placebo-Controlled, Double-Blind Trial.

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
backgroundAcute kidney injury (AKI) as a result of iodinated contrast media (CM) has been linked to CM-induced renal ischemia and toxic effects on endothelial cells (EC). The recombinant human C1 inhibitor (rhC1INH) has been shown to influence EC activation.
methodsSecondary analysis of 74/77 (96%) participants of a double-blind, randomized, and placebo-controlled study that assessed the effect of rhC1INH on AKI. E-selectin, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule (VCAM-1), and CC-chemokin-ligand-5 (CCL5) were determined in frozen blood samples over 48 h and analyzed according to the treatment group and renal outcomes.
resultsThe mean age was 76.7 years, and 37 patients each received rhC1INH and placebo, respectively. In the entire study population, minor differences in median EC activation markers/CCL5 concentrations during the first 48 h compared to baseline were observed (e.g., E-selectin 27.5 ng/mL at baseline vs. 29.7 ng/mL on day 1, CCL5: 17.7 ng/mL at baseline vs. 32.2 ng/mL on day 2). Absolute changes in ICAM-1/E-selectin concentrations correlated with a higher peak change in urinary NGAL concentrations. However, AKI was not associated with significant changes in EC markers/CCL5. Last, no significant differences in serum concentrations of EC activation markers/CCL5 were evident between the placebo and the rhC1INH group.
conclusionsCM administration during coronary angiography only mildly activated ECs within the first 48 h, which does not explain subsequent AKI. The administration of rhC1INH was not associated with a reduction of EC activation or CCL5.
