Complete Blood Count in Delayed Graft Function: A Narrative Review.
Review in Annals of transplantation, 2026. 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
Delayed graft function (DGF) is a common and critical complication following kidney transplantation, marked by acute kidney injury necessitating dialysis within the first postoperative week. Early detection of patients at risk is crucial for optimizing perioperative management and enhancing graft outcomes. While novel biomarkers have been suggested, their clinical application remains limited. This review explores the potential of complete blood count (CBC) parameters and derived indices as cost-effective, accessible alternatives. This narrative review synthesizes findings from studies examining the relationship between CBC parameters - such as hemoglobin, white blood cell count, and platelet count, and hematological indices like neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) - and DGF risk in kidney transplantation. A comprehensive literature search was conducted across major biomedical databases using targeted keywords. Selected studies were analyzed to assess the predictive value, underlying mechanisms, and clinical utility of these parameters. This review highlights a significant association between specific CBC parameters and DGF risk. Notably, low pre- or perioperative hemoglobin levels, significant perioperative hemoglobin drops, elevated pre- or post-transplant NLR, and altered PLR are correlated with increased DGF risk. These associations are thought to reflect underlying pathophysiological mechanisms, including inflammatory responses, ischemia-reperfusion injury, and immune cell activation. However, variability in study design, sampling time points, donor types, and DGF definitions complicates interpretation, underscoring the need for prospective multicenter validation. CBC-derived parameters demonstrate promising associations with DGF risk, particularly low pre-transplant hemoglobin levels and perioperative declines >1.3 g/dL. Preoperative NLR >3.5 and postoperative leukocyte ratios may aid in early graft dysfunction detection. Despite inconsistent evidence for platelet-related indices, further prospective multicenter studies are essential to confirm clinical utility and establish standardized cutoff values.
