Simple and Effective Techniques to Minimise Contrast Dosage During Infrarenal Endovascular Aneurysm Repair.

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
Introduction: Endovascular aortic repair (EVAR) is the standard of care for abdominal aortic aneurysms owing to its minimally invasive nature and favourable peri-operative outcomes. However, reliance on iodinated contrast media (ICM), including unnecessarily high volumes, raises concerns regarding contrast induced nephropathy, particularly in patients with pre-existing renal impairment. This study describes simple, pragmatic, and cost effective strategies to minimise ICM use during EVAR and presents an institutional experience. Technique: Three contrast injection strategies were applied, designated the wet protocol (ICM only), mixed protocol (ICM + carbon dioxide [CO Discussion: An exemplar analysis was undertaken of 150 patients (98 men and 52 women, mean age 76 ± 7 years) who underwent infrarenal EVAR between March 2017 and June 2025 by author A.C., applying these contrast protocols. These were used accordingly: wet protocol (
