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
In this study, we investigated the association between serum 25-hydroxyvitamin D (25(OH)D) levels and fracture risk in patients undergoing hemodialysis. Our findings suggest that maintaining adequate serum 25(OH)D levels may be important for preserving bone health even in patients undergoing hemodialysis with impaired renal activation of vitamin D. PURPOSE: Vitamin D deficiency and fragility fractures are highly prevalent among patients undergoing hemodialysis. Low serum 25(OH)D levels are associated with an increased risk of fractures in the general population; however, whether this association persists in patients undergoing hemodialysis with suppressed renal activation of 25(OH)D remains unclear.
methodsSerum 25(OH)D levels were measured in 292 stable outpatients undergoing maintenance hemodialysis. The association between baseline 25(OH)D status and the incidence of new fragility fractures was investigated.
resultsDuring the median follow-up period of 24 months, 49 (16.8%) fractures occurred. Multivariate Cox regression analyses revealed the significant association of a 10 nmol/L increment in serum 25(OH)D levels with a reduced risk of fractures (adjusted hazard ratio [aHR] 0.83, 95% confidence interval [CI] 0.68-0.99, p = 0.046). When patients were stratified by the median 25(OH)D level, the cumulative fracture incidence rates were 24.3% and 11.9% (aHR 1.87, 95% CI 1.02-3.42, p = 0.041) in the lower- and higher-25(OH)D groups, respectively.
conclusionLower serum 25(OH)D levels were independently associated with an increased risk of fracture, regardless of traditional fracture risk factors or variables affecting vitamin D status in patients undergoing hemodialysis with impaired renal vitamin D activation. This finding suggests that circulating 25(OH)D levels may serve as a predictor of fracture risk in patients undergoing hemodialysis.
