Hematological indicators and ocular parameters in patients with non-arteritic anterior ischemic optic neuropathy.
Article in International ophthalmology, 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
purposeTo evaluate the clinical significance of hematological indicators and ocular parameters in patients with non-arteritic anterior ischemic optic neuropathy (NAION).
methodsIn this retrospective study, 31 NAION patients and 117 age- and gender-matched control subjects were enrolled in 2019-2024. All participants underwent a comprehensive eye examination and received a complete blood count. Hematological parameters (leukocytes, neutrophils, lymphocytes, monocytes, mean platelet volume, platelet distribution width (PDW), activated partial thromboplastin time, and international normalized ration) and ocular parameters including axial length and anterior chamber depth were collected. Analysis of variance, multivariate logistic regression and a receiver operating characteristic curve analysis were used for statistics.
resultsHematological indicators and inflammatory markers, including systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ration (NLR), white blood cell, monocytes, and PDW values of NAION patients were notably higher than those of the control groups (p < 0.05). Multivariate logistic regression identified a significant correlation only between higher levels of PDW and NAION (p = 0.001). The optimal cut-off value of PDW was 14.65, featuring 75.9% sensitivity and 66.4% specificity. However, there was no statistical difference between the NAION patients and the controls in ocular parameters.
conclusionInflammatory hematological indicators were significantly increased in NAION patients, and PDW might serve as a new marker for the clinical management of NAION patients.
