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
Brief rationale: The effectiveness of bisphosphonates versus denosumab after hip fracture, especially in people with dementia or frailty, remains unclear. MAIN
resultBisphosphonates were associated with a higher rate of subsequent fracture and a lower mortality rate in men. There are no differences by dementia or frailty status. Significance of the paper: Sex may influence antiresorptive treatment choice. PURPOSE: The relative effectiveness of first-line antiresorptive medications post-hip fracture in people with dementia or frailty is not understood. We investigated the risk of a subsequent fracture and death in people prescribed bisphosphonates or denosumab following hip fracture, including in people with dementia and frailty.
methodsParallel population-based cohort studies were conducted in Australia, Hong Kong, Taiwan, and the United Kingdom. People aged ≥ 50 prescribed or dispensed a bisphosphonate or denosumab within 60 days of discharge following their first hip fracture were included. Subgroup analyses were conducted for people with dementia, frailty, women, and men. Outcomes were second hip fracture, any subsequent fracture, and death. Inverse probability of treatment weighted Cox and competing risk models were used to estimate hazard ratios (HR) and subdistribution hazard ratios (sHRs) with 95% confidence intervals (CIs) for outcomes. Results across jurisdictions were combined using meta-analyses.
resultsThere were 18,292 bisphosphonate users and 8560 denosumab users. Bisphosphonates versus denosumab were associated with similar rates of second hip fracture (sHR 1.13; 95% CI 0.76-1.69) and mortality (HR 0.99; 95% CI 0.94-1.04), but higher rates of any subsequent fracture (sHR 1.16; 95% CI 1.11-1.21), including in men (sHR1.27; 95% CI 1.15-1.42) but not in women (sHR 1.23; 95% CI 1.00-1.52), or in people with dementia or frailty. Men who used bisphosphonates had lower rates of mortality (HR 0.90; 95% CI 0.81-0.99) than men who used denosumab.
conclusionBisphosphonate users had higher rates of subsequent fracture than denosumab users. Mortality rates in men were lower with bisphosphonates than denosumab. There were no significant differences by dementia and frailty status.
