Weekend discharge after hip fracture surgery is associated with increased 30-day mortality. A retrospective observational study of 35,138 hip fractures reported to the Norwegian Hip Fracture Register.

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
purposeThe influence of discharge timing after hip fracture surgery has been sparsely investigated. We aimed to investigate whether time of discharge influence 30-day mortality, and secondarily 1-year mortality and 30-day readmission risk after hip fracture surgery.
methodsData from 35,138 hip fracture patients aged ≥ 65 and with length of stay (LoS) ≤ 14 days reported to the Norwegian Hip Fracture Register 2008 to 2018 were analyzed. Cox regression analyses, adjusted for age groups, sex, ASA class, cognitive function, fracture type, and type of surgery were used to calculate mortality risk after discharge on weekdays compared to weekends (Friday 18:00 to Monday 08:00). Patients were grouped by age, cognitive function, ASA class, and discharge destination.
resultsMean age was 83 years, 71% were women, and 61% had ASA class ≥ 3. Patients discharged on weekends were marginally older, more often ASA class ≥ 3, cognitively impaired, and had shorter LoS than patients discharged on weekdays. Weekend discharge was associated with increased 30-day mortality (HRR 1.4, 95% CI 1.3-1.6; p < 0.001) and 1-year mortality (HRR 1.2, CI 1.2-1.3; p < 0.001) compared to weekday discharge. Sub-analyses showed increased 30-day mortality for all age groups except 65-74 years, all ASA groups, patients with and without cognitive impairment, patients discharged to nursing homes and the most common surgical methods. No statistically significant difference in 30-day readmission risk was found after weekend discharged compared to weekday discharge.
conclusionWeekend discharge for hip fracture patients was associated with increased 30-day and 1-year mortality, but did not influence overall 30-day readmission risk.
