1 · What the graph read from it

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.

2 · The registry

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 elderly dialysis patients are associated with increased postoperative complications and mortality, but large-scale analyses remain limited. This retrospective cohort study utilized Japan's nationwide Diagnosis Procedure Combination database (2016-2022). After applying 1:1 propensity score matching, 9,601 chronic hemodialysis patients were compared with 9,601 non-dialysis patients for postoperative outcomes, including venous thromboembolism (VTE), cognitive dysfunction, and in-hospital mortality. The study cohort included only patients receiving chronic maintenance hemodialysis; peritoneal dialysis patients were not included. Statistical significance was defined as a p < 0.001. The in-hospital mortality rate was 5.2% in dialysis patients versus 1.7% in non-dialysis patients. Thirty-day postoperative survival was 99.2% in non-dialysis patients and 97.5% in dialysis patients. Dialysis patients had higher odds of postoperative cognitive dysfunction (OR: 1.944; 95% CI: 1.515-2.495, p < 0.0001) and in-hospital mortality (OR: 3.288; 95% CI: 2.743-3.941, p < 0.0001). The incidence of VTE was lower among dialysis patients. Male sex, older age, and lower BMI were also independent risk factors for mortality. Dialysis is associated with markedly worse outcomes following hip fracture surgery. Comprehensive perioperative management and preventive strategies are essential to improve prognosis in this high-risk population.
