Neutrophil-to-lymphocyte ratio as a predictor of in-hospital mortality in elderly emergency patients: a retrospective study from Southern Iran.
Article in BMC geriatrics, 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
backgroundMortality risk stratification in older emergency department (ED) patients remains challenging in resource-limited settings, particularly among frail elderly with multiple comorbidities. This study evaluated the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in Southern Iran.
methodsIn this retrospective single-center study conducted between March 2021 and March 2022, we analyzed records of 2,540 consecutively admitted patients aged ≥ 65 years to an academic ED in Southern Iran. NLR was calculated from initial complete blood counts.
resultsAn NLR > 3.75 predicted in-hospital mortality with 52.2% sensitivity and 75.8% specificity (AUC = 0.655; 95% CI: 0.636–0.674; p < 0.001). Multivariate analysis confirmed NLR as an independent predictor (adjusted OR = 1.77; 95% CI: 1.28–2.44). An inverse association was observed between hypernatremia and mortality risk (OR = 0.68; 95% CI: 0.57–0.82).
conclusionsNLR > 3.75 may serve as a supportive and low-cost indicator for mortality risk stratification in elderly emergency patients; however, it should not be considered a stand-alone triage tool. The unexpected inverse association with hypernatremia warrants cautious interpretation and validation in future studies.
