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

There is ongoing effort to discharge patients early after hip fracture surgery to reduce the medical and economic burden. We tried to find whether there is any related side effect, and discovered that early discharge, especially before 10 days after surgery, is associated with higher mortality.

introductionThe aim of this study was to analyze the association between the length of hospital stay after hip fracture and 1-year mortality in older adults aged ≥ 65 years old.

methodsWe conducted a retrospective cohort study using the Korean National Health Insurance Service data to identify patients who were discharged after hip fracture surgery from 2007 to 2009 among 487,460 older adults of age ≥ 65 years. The lengths of stay involving hip fracture surgery were categorized at 10-day interval, and analyzed in relation to 1-year mortality from the date of hospital discharge.

resultsA total of 4213 patients were discharged after hip fracture surgery, of whom 604 (14.3%) died within 1 year of discharge. The average length of stay was 30.7 days (standard deviation 24.5 days). The 1-year mortality was the highest for the length of stay ≤ 10 days group at 21.7%, followed by 15.2%, 14.3%, 13.3%, and 12.4% for > 40, 21-30, 31-40, and 11-20 days groups, respectively (p value 0.05). On Cox proportional hazard regression, the adjusted hazard ratio for length of stay ≤ 10 days group was 1.56 (95% confidence interval 1.14-2.12) against the reference group (11-20 days), while other groups did not show statistical significance. Higher risk of death was associated with increasing age, male gender, Charlson comorbidity index ≥3, subtrochanteric fracture, and discharge to tertiary care hospitals and long-term care hospitals.

conclusionOlder adults discharged within 10 days of hospital admission for hip fracture surgery have higher 1-year mortality after discharge.
