Effect of renal dialysis on mortality and complications following hip fracture surgery in elderly patients: A population based retrospective cohort study.
Observational study in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Hip fractures in older patients requiring dialysis are associated with high mortality. The primary aim of this study was to evaluate the specific burden of dialysis on 30-day mortality following hip fracture surgery. The secondary aim was to determine the burden of dialysis on overall survival as well as several postoperative complications.A retrospective cohort study was conducted using data from the Korean National Health Insurance Research Database. Patients were aged ≥65 years and underwent hip fracture surgery during the period from 2009 to 2015. To construct a matched cohort, each dialysis patient was matched to 4 non-dialysis patients based on age, sex, hospital type, anesthesia type, and comorbidities. Survival status was determined 30 days after surgery and at the end of the study period.In total, 96,289 patients were identified. Among them, 1614 dialysis patients were included and matched to 6198 non-dialysis patients. During the 30-day postoperative period, there were 102 mortality events in the dialysis group and 127 in the non-dialysis group, for an adjusted hazard ratio of 3.12 (95% confidence interval, 2.42-4.09). Overall, by the end of the study period, there were 1120 mortality events in the dialysis group and 2731 in the non-dialysis group, for an adjusted hazard ratio of 1.97 (95% confidence interval, 1.83-2.1). These findings may be limited by the characteristics of the administrative database.The 30-day mortality rate was 3-fold higher in the dialysis group than in the non-dialysis group, while the overall mortality rate was approximately 2-fold higher in the dialysis group than in the non-dialysis group. These findings suggest that caution in the perioperative period is required in dialysis patients undergoing hip fracture surgery. The results of our study represent only an association between dialysis and mortality. Further studies are necessary to investigate the possible causal effect of dialysis on mortality and complications after hip fracture surgery.
