Psychometric Performance of Clinician- and Patient-Reported Outcome Measures in Surgically Treated Thoracic Myelopathy: A Multicenter Prospective Study.
Article in Global spine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 prospective observational study.ObjectivesTo determine the responsiveness, reliability, and construct validity of commonly used clinician-reported and patient-reported outcome measures in surgically treated thoracic myelopathy, a condition for which standardized outcome assessment has not been established.MethodsAdults undergoing surgery for MRI-confirmed thoracic myelopathy were prospectively enrolled at nine tertiary centers. Clinician-reported measures included the Japanese Orthopaedic Association (JOA) score, a thoracic-adapted JOA subtotal (JOAt), and the modified JOA (mJOA). Patient-reported outcomes included the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) and EuroQOL 5-dimension (EQ-5D). Assessments were performed preoperatively and at 3-6 months postoperatively. Internal responsiveness was evaluated using Wilcoxon's r, test-retest reliability using ICC(1,1), and construct validity using Spearman's correlation with EQ-5D.ResultsFifty-one patients were included (mean age 65.6 years; 59% male). Significant postoperative improvement was observed across major clinician-reported and patient-reported outcomes. Large internal responsiveness was demonstrated for JOA (r=0.64), JOAt (0.63), mJOA (0.68), and JOACMEQ lower-extremity function (LF) (0.59). Test-retest reliability was high for JOA, JOAt, mJOA, JOACMEQ-LF, and EQ-5D (ICC range 0.78-0.85). JOACMEQ-LF showed the strongest construct validity with EQ-5D at both baseline (ρ=0.62) and follow-up (ρ=0.72).ConclusionsJOAt, mJOA, and JOACMEQ lower-extremity function demonstrated robust psychometric performance in thoracic myelopathy. These measures represent suitable candidates for standardized outcome assessment and provide a methodological foundation for future clinical studies and guideline development in this under-studied condition.
