Association between systemic inflammatory markers and otosclerosis: a retrospective case-control study.
Article in Frontiers in neurology. 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
Objective: Otosclerosis is a localized metabolic bone disease of the otic capsule with an inflammatory component. This study investigated whether otosclerosis is associated with alterations in systemic inflammatory indices, namely the Neutrophil-to-Lymphocyte Ratio (NLR) and the Systemic Immune-Inflammation Index (SII). Materials and methods: This retrospective case-control study included 52 patients with otosclerosis who underwent stapedotomy and 50 control subjects who underwent septoplasty for isolated nasal septal deviation between January 1, 2023 and January 1, 2024. Preoperative venous blood samples were obtained within 7 days before surgery, between 08:00 and 10:00 a.m. after overnight fasting. Complete blood counts were analyzed using an automated hematology analyzer (UniCel DxH 800, Beckman Coulter, USA). SII was calculated as (platelet × neutrophil)/lymphocyte, and NLR as neutrophil/lymphocyte. Group comparisons, multivariable logistic regression (adjusted for age and sex), and ROC curve analyses were performed. Results: SII was significantly higher in the otosclerosis group than in controls (599.1 ± 154.3 vs. 503.5 ± 114.8; Conclusion: SII was independently associated with otosclerosis, suggesting a subtle systemic immune-inflammatory signature. Given the borderline significance and moderate ROC performance, these findings should be interpreted as exploratory and require confirmation in larger prospective cohorts.
