The Osteoporotic Vertebral Fracture Conservative Treatment Prognosis Score (OVF-CTPS): Development and Validation of a Prognostic Tool for Conservative Treatment of OVFs Based on a Prospective Cohort Study.
Article in Spine, 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
designA prospective cohort study (Level III).
objectiveTo develop and validate a clinical scoring system (Osteoporotic Vertebral Fracture Conservative Treatment Prognosis Score, OVF-CTPS) for predicting the prognosis of conservative treatment in patients with osteoporotic vertebral fractures (OVFs), addressing clinical uncertainty in treatment selection. SUMMARY OF BACKGROUND DATA: OVFs face uncertainty in choosing conservative versus surgical management. Ten percent to 40% of patients have conservative treatment failure ( e.g. , nonunion, collapse). Existing classification systems lack prognostic value, highlighting the need for a practical predictive tool.
methodsTwo hundred one patients with acute OVFs undergoing conservative treatment were prospectively followed for 6 months. Baseline assessments included demographics, pain, quality of life measures, and multimodal imaging (X-ray, CT, and MRI). The primary outcome was conservative treatment failure. Independent predictors were identified using multivariate logistic regression and weighted to create the OVF-CTPS, which was validated using receiver operating characteristic (ROC) analysis.
resultsThe conservative treatment failure rate was 29.9%. Six independent predictors were identified: Sugita "bow-shaped" or "concave" type, standing vertebral collapse degree <80%, middle column/posterior wall injury, T2WI "diffuse low" signal, STIR linear black signal, and basivertebral foramen involvement. The OVF-CTPS (range: 0-13) demonstrated excellent predictive performance (AUC=0.918). At an optimal cutoff score of 6, the sensitivity was 91.3% and the specificity was 84.0%. The low-risk group (score <6) had a 96.3% treatment success rate, while the high-risk group (score ≥6) had a success rate of 32.3.
conclusionThe OVF-CTPS is a validated prognostic tool that integrates fracture morphology, injury severity, and MRI-based perfusion markers. It accurately stratifies patients based on their risk of conservative treatment failure, enabling clinicians to identify low-risk patients suitable for conservative care and high-risk patients who may benefit from early surgical evaluation.
