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 Post-operative acute kidney injury (AKI) has a significant impact on patients and healthcare systems. We studied the impact of the implementation of a comprehensive multidisciplinary guideline and risk assessment tool on the need for dialysis and hospital length of stay (LOS) in patients undergoing elective surgery. Methods We performed a single-center retrospective analysis of patients undergoing elective surgery before and after the implementation of a comprehensive multidisciplinary guideline for decreasing post-operative AKI from January 2021 to August 2024. The guideline utilized a pre-operative risk assessment tool to predict patients at high risk for post-operative AKI and utilized intra-operative and perioperative interventions to improve perfusion and volume status. Patients were categorized into pre (PRE) - January 2021 to May 2021, and post-implementation (POST) - June 2023 to August 2024, cohorts. The primary outcome was the need for dialysis. Secondary outcomes were mortality, hospital LOS, ICU LOS, and ventilator days. Results Of the 11,006 patient visits, 7,398 (67%) were in the PRE period, and 3,608 (33%) were in the POST period. The POST group was older (age in years POST: 63.9 vs. PRE: 62.9) and had a lower incidence of CAD (POST: 21.2% vs. PRE: 25.9%) and hypertension (POST: 47.5% vs. PRE: 52.8%). After matching, the POST group had longer procedure times and higher intra-operative fluids, and the distribution of surgical specialties was different. The POST had lower mortality (0.5% vs 1.0%, p=0.04) and shorter LOS in the hospital (median: three vs four days), in the ICU (eight vs nine days), and on the ventilator (one vs two days). In the multivariable regression analysis, the POST cohort was significantly associated with a reduction in AKI incidence (OR: 0.83, 95% CI: 0.69, 0.99; p = 0.04). Conclusion Implementing a multidisciplinary process to improve post-operative AKI may improve AKI and hospital LOS. Targeted interventions to reduce AKI should be further examined.
