Age predicts long-term functional outcomes following vertebroplasty for osteoporotic vertebral compression fractures: a retrospective cohort study.

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: Vertebroplasty provides effective pain relief for osteoporotic vertebral compression fractures; however, determinants of long-term functional recovery remain incompletely defined. This study aimed to evaluate baseline predictors of long-term patient-reported outcomes following vertebroplasty. Methods: Ninety-two patients who underwent percutaneous vertebroplasty between 2010 and 2022 with complete patient-reported outcome measures (PROMs) at baseline, 6 months, and 2 years were included. The primary outcome was Short Form-36 (SF-36) Physical Function at 2 years. Multivariable linear regression models adjusted for baseline PROMs were used to evaluate associations with age, sex, vertebral region, and number of treated levels. Results: Mean age was 76.5±8.4 years, and 82.6% were female. Significant improvements were observed in Oswestry Disability Index (ODI) scores (77.3 to 25.3), SF-36 Physical Function (9.2 to 41.8), and visual analogue scale (VAS) back pain scores (8.0 to 1.7) at 2 years (all P<0.001). Increasing age was independently associated with poorer 2-year SF-36 Physical Function [β=-17.45 per 10-year increase; 95% confidence interval (CI): -24.43 to -10.47; P<0.001]. Procedural variables were not associated with postoperative outcomes. Baseline physical function demonstrated moderate correlation with postoperative outcomes (r=0.40-0.44) but was not independently predictive after adjustment. Conclusions: Vertebroplasty was associated with sustained improvement in pain and function. Increasing age was the strongest observed independent predictor of poorer long-term physical function within this cohort, whereas procedural variables were not significantly associated with postoperative outcomes. These findings suggest that long-term functional recovery following vertebroplasty may be associated more strongly with patient-related than procedural factors within this cohort.
