Time Interval From Coronary Angiography to Bypass Surgery and Risk of Postoperative Acute Kidney Injury: A Cross-Sectional Study.
Article in Health science reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and Aims: The association of the time interval between coronary angiography and coronary artery bypass surgery (CABG) with postoperative acute kidney injury (AKI) remains uncertain. We evaluated and compared the risk of developing AKI after CABG in two groups of patients with a time interval between coronary angiography and CABG of less than 7 days and more than 7 days. Methods: This cross-sectional study was conducted on 171 patients who needed to undergo CABG for the first time within 1 month after coronary angiography. Overall, 85 patients underwent operation within 7 days of angiography (Group A) and 86 within 7 days to 1 month after angiography (Group B). AKI was defined using Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE) criteria. Results: Median preoperative biomarkers (serum creatinine, blood urea nitrogen) were similar between groups and did not significantly change postoperatively. The incidence of AKI was 5.8% ( Conclusion: While a 7-day interval between angiography and CABG did not significantly impact AKI incidence, we observed a non-significant trend toward higher AKI rates with shorter intervals. Our limited sample size and low overall AKI incidence (5.8%) warrant larger studies to clarify this relationship, particularly in patients with reduced left ventricular function.
