The diagnostic value of prognostic nutritional ındex and controlling nutritional status score in differentiating retinal vein occlusion.
Article in International ophthalmology, 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
purposeTo evaluate the diagnostic utility of the Prognostic Nutritional Index and Controlling Nutritional Status score in patients with retinal vein occlusion.
methodsIn this retrospective case-control study, 55 patients diagnosed with retinal vein occlusion between Jan 2019 and May 2024 and 110 healthy controls were examined. Demographic data, systemic comorbidities, laboratory parameters, the Prognostic Nutritional Index and the Controlling Nutritional Status score were compared between groups. Binary logistic regression analysis was used to identify independent predictors of retinal vein occlusion; receiver operating characteristic curve analysis was used to evaluate the discriminative performance of Prognostic Nutritional Index and Controlling Nutritional Status score.
resultsThe mean age (p = 0.311), and gender distribution (p = 0.226) were similar in retinal vein occlusion and control groups. Hypertension was more prevalent in retinal vein occlusion group (89.1% vs. 60.9%, p < 0.001). Mean Prognostic Nutritional Index (45.62 ± 1.52 vs. 45.59 ± 2.41, p = 0.557) and median Controlling Nutritional Status scores (0 vs. 0, p = 0.129) were similar between groups. In multivariate logistic regression analysis, only hypertension independently predicted retinal vein occlusion (OR = 5.12; p = 0.001). Prognostic Nutritional Index demonstrated poor discrimination (AUC = 0.528; p = 0.557) for retinal vein occlusion.
conclusionsPrognostic Nutritional Index and Controlling Nutritional Status score, which are valuable prognostic biomarkers in some chronic systemic and ophthalmologic diseases, could not distinguish retinal vein occlusion cases from controls. Hypertension remains the principal modifiable risk factor for retinal vein occlusion.
