High neutrophil-to-lymphocyte ratio as a cost-effective marker of acute kidney injury and in-hospital mortality after cardiac surgery: a case-control study.
Article in Renal failure, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundInflammation is one of the important pathophysiological characteristics of acute kidney injury (AKI) after cardiac surgery. The aim was to explore the relationship between preoperative neutrophil-to-lymphocyte ratio (NLR), a simple and cost-effective maker of inflammatory response, and AKI after cardiac surgery. Furthermore, whether the NLR affected in-hospital mortality was also investigated.
methodsThe electronic medical records of patients from January 1, 2006 to December 31, 2018 undergoing cardiac surgery were utilized. The interest outcome was AKI, defined as the criteria of Kidney Disease Improving Global Outcomes (KDIGO), and other outcomes were severe AKI (KDIGO stage ≥2) and in-hospital mortality. Logistic regression was utilized to assess the association of preoperative NLR with outcomes while adjust for potential confounders.
resultsTotally, 23,638 patients were included. The incidence of AKI was 27.6%. The NLR was significantly greater in patients with AKI compared to those without. As the nonlinear relationship between NLR and AKI indicated by restricted cubic spline, NLR was analyzed as a categorical variable with the cutoff value of five. Multivariate analysis demonstrated that NLR > 5 was significantly associated with an increased risk of AKI, with an odds ratio of 5.046 (95% confidence interval, 4.589 to 5.548), when compared to patients with NLR ≤ 5. Furthermore, high NLR was also an independent risk factor for severe AKI and in-hospital mortality.
conclusionsA higher preoperative NLR was increased the risk of AKI, severe AKI, and in-hospital mortality after cardiac surgery, which may be helpful for stratifying patients to develop individualized treatment.
