NLR and PLR as Adjunctive Markers of MRI-Derived Vertebral Bone Quality in a Preoperative Lumbar Cohort.
Article in Therapeutics and clinical risk management, 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
Background: MRI-derived vertebral bone quality (VBQ) rises with marrow fat and denotes poorer bone integrity. We examined whether simple inflammatory ratios-neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR)-relate to VBQ in degenerative lumbar disease. Methods: We retrospectively studied 200 patients aged ≥50 years who underwent surgery between January 2022 and January 2024. VBQ was calculated on mid-sagittal T1-weighted MRI using vertebral and cerebrospinal-fluid regions of interest. Associations were tested with Spearman correlations and multivariable linear regression adjusting for age, sex, smoking, diabetes, and body mass index (BMI). Results: Among 200 patients (mean age = 64.8 ± 8.7 years), those with higher VBQ values (indicating poorer bone quality) were older and had higher NLR and PLR (all p<0.001). VBQ showed significant positive correlations with age ( Conclusion: Preoperative NLR and PLR were independently associated with higher MRI-derived VBQ and may aid imaging-based risk stratification; prospective validation with calibrated thresholds is needed.
