Optimized OF-Score- Therapy Prediction in Successfully Treated Patients With Osteoporotic Spine Fractures Using Minimal Clinically Important Difference.
Article in Global spine journal, 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
Study DesignMulticenter study with prospective collected data.ObjectivesThis study investigates the relationship between individual score components and treatment success, defined by achieving Minimal Clinically Important Difference (MCID) thresholds in functional outcomes, using multicenter prospectively collected data. This work aimed to optimize the OF-Score while maintaining its original structure. By using outcome-oriented data, we refined this established decision-support tool to improve its predictive accuracy for successful clinical outcomes.MethodsData from 518 patients from the EOFTT study with osteoporotic vertebral fractures were analyzed. Only patients with clinically successful outcomes, defined by improvement beyond MCID thresholds in functional scores after conservative or surgical treatment, were selected from this cohort. Optimization was performed using a data-driven reweighting approach combined with structured clinical expert evaluation, adjusting variable weights within predefined limits to improve alignment with successful therapies.ResultsThe subset data of 374 successfully treated patients were analyzed. Before optimization, the OF-Score showed an accuracy of 73%, with pain and mobilization being the most important parameters. After optimization, the OF-Score showed an accuracy of 80.7% (sensitivity 85.2%, specificity 71.2%). The number of nonapplicable (indifferent) therapy recommendations dropped from 144 (37%) to 72 (19%). A threshold of 5 points provided optimal discrimination between conservative treatment (≤5) and surgical treatment (>5).DiscussionThe optimized OF-Score, targeted weight adjustments, improves the alignment between clinical recommendations and treatment success. This refinement enhances the score's predictive accuracy for treatment responders while maintaining the simple, practical structure.
