Vertebral Fractures Identified by Lateral Spine Dual Energy X-Ray Absorptiometry Scans and Mortality Risk in Adults.
Article in Journal of bone metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundVertebral fractures identified by radiographic morphometry are associated with increased mortality risk. However, there is limited data regarding the association between vertebral fractures detected by lateral spine dual energy X-ray absorptiometry (DXA) scans and the risk of mortality.
methodsThe present study was based on data from participants aged 40 years and older in the 2013 to 2014 cycle of the National Health and Nutrition Examination Survey (NHANES). Vertebral fracture assessment (VFA) performed using lateral spine DXA scans was used to provide fracture information of the vertebrae from T4 to L4. Vertebral fracture severity was categorized according to Genant's semiquantitative technique and the NHANES 2019 public-use linked mortality files were used to determine mortality status.
resultsOf 3,219 participants, the prevalence of vertebral fractures identified by VFA was 5.5% (95% confidence interval [CI], 4.7-6.5). During a median follow-up of 71.0 months, 277 participants died, 18.2% (95% CI, 12.2-26.3) with vertebral fractures and 6.3% (95% CI, 5.0-8.0) without fractures (p<0.0001). Cox regression analysis demonstrated that participants with moderate to severe vertebral fractures (>25% height loss) were 1.7 times more likely to die compared with their counterparts without (hazard ratio [HR], 1.79; 95% CI, 1.05-3.04). Notably, in a subgroup analysis, older adults (HR, 2.16; 95% CI, 1.41-3.30) and men with vertebral fractures (HR, 2.28; 95% CI, 1.49-3.47) had a 2-fold greater mortality risk compared to those without vertebral fractures.
conclusionsVertebral fracture severity identified by VFA was significantly associated with greater all-cause mortality risk. This association was also observed among men and older adults with any baseline vertebral fractures.
