Outcomes of isolated hip fractures in people with Parkinson's disease: An observational cohort study using propensity score methods.
Article in Journal of Parkinson's disease, 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
BackgroundPeople with Parkinson's disease (PwP) have a high risk of hip fracture and the outcomes of PwP in Australia with hip fractures are unknown.ObjectiveTo describe the characteristics of PwP who present with a hip fracture and to examine the association between Parkinson's with acute hospital outcomes, mortality and discharge destination.MethodsWe conducted a cohort study of individuals with an isolated proximal femur fracture using the Victorian Orthopaedic Trauma Outcomes Registry (Australia) from 2016 to 2022. Demographic characteristics, comorbidities, fracture types, acute hospital length of stay, discharge destination and 30-day and 12-month mortality data were extracted. Inverse-probability weighting with estimated propensity scores determined the association of Parkinson's with outcomes, using a logistic regression model that included covariates and injury characteristics.ResultsOf 5,553 patients, 208 (4%) had PD, with a mean age of 79.9 years (SD 12.9). After propensity score adjustment, there was no association between Parkinson's and ICU admission (OR 1.89; 95% CI 0.67, 5.34), acute length of stay (adjusted median 6.9 vs 7.7) and 12-month mortality rates (OR 1.25; 95% CI 0.85, 1.82). PwP were more likely to be discharged to rehabilitation than home (RR 2.04; 95% CI 1.12, 3.74).ConclusionsWe did not observe a statistically significant difference in acute hospital outcomes between the two cohorts, including length of stay. This is encouraging as avoiding prolonged hospitalisation reduces health care costs and risk of hospital-related harms. However, these findings may reflect limited statistical power and differences between groups cannot be excluded. Further research is also indicated to explore post-care discharge pathways and longer-term functional outcomes of this group.
