Comparable 2-year functional outcomes following vertebroplasty for thoracic and lumbar osteoporotic vertebral compression fractures: a retrospective cohort study.
Article in Asian 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
designRetrospective cohort study. PURPOSE: To compare short- and medium-term patient-reported outcome measures (PROMs) between thoracic and lumbar percutaneous vertebroplasty (PVP) cohorts for osteoporotic vertebral compression fractures (OVCFs). OVERVIEW OF LITERATURE: PVP is well-established for pain relief in OVCF; however, whether clinical outcomes vary by the anatomical location of the treated vertebrae, remains unclear.
methodsNinety patients who underwent PVP between January 2010 and August 2022 with complete 2-year PROM follow-up were included and stratified into thoracic (n=33) and lumbar (n=57) cohorts. Outcomes included the Oswestry Disability Index (ODI), North American Spine Society (NASS) Neurogenic Symptom score, Visual Analog Scale (VAS) pain score, and Short Form-36 (SF-36) domains. Between-group comparisons were assessed using Wilcoxon rank-sum tests, and effect sizes were summarized using Cliff's delta. Minimal clinically important difference (MCID) achievement was assessed for ODI, VAS Back Pain, and VAS Leg Pain. Multivariable linear regression examined the independent effect of vertebral region after adjustment for age, sex, race, number of vertebral levels treated, and baseline PROMs, with Benjamini-Hochberg false-discovery-rate (FDR) correction applied for multiple comparisons.
resultsThe mean age was 76.4±8.5 years, and 83.3% of patients were female. No significant between-group differences were observed in ODI, NASS score, VAS pain score, or any SF-36 domain at 6 months or 2 years (p>0.05). MCID achievement rates for ODI and VAS Back Pain were high and comparable between groups at both follow-up points, exceeding 87%. On adjusted regression, the vertebral region was not an independent predictor of any postoperative PROM after FDR correction.
conclusionsThoracic and lumbar vertebroplasty yielded comparable 2-year PROMs with no statistically significant differences detected between cohorts. These findings suggest that the vertebral region may not be a major determinant of patient-reported recovery following vertebroplasty for OVCFs. However, residual confounding, attrition, and absent radiographic variables preclude definitive conclusions regarding clinical equivalence.
