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

backgroundThere is a perception that income-based disparities are present in most countries but may differ in magnitude. However, there are few international comparisons that describe income-based disparities across countries and none that focus on hip fractures.

objectiveTo compare treatment patterns and outcomes of high- and low-income older adults hospitalized with hip fracture across six high-income countries.

designRetrospective serial cross-sectional cohort study.

participantsAdults aged ≥ 66 years hospitalized with hip fracture from 2013 to 2019 in Canada, England, Israel, the Netherlands, Taiwan, and the USA using population-representative patient-level administrative data. MAIN MEASURES: Older adults in the top and bottom income quintiles within countries were compared on 30-day and 1-year mortality, treatment approaches, hospital length of stay (LOS), 30-day readmission rates, time to surgery, and discharge disposition. KEY

resultsAnnual age- and sex-standardized incidence rates of hip fracture were higher for low- than for high-income populations in all countries except in the USA. In all countries, adjusted 1-year mortality was lower for high-income than low-income patients, with the largest difference in Israel (- 10.0 percentage points [95% confidence interval [CI], - 15.2 to - 4.8 percentage points]). Across countries, utilization of total hip arthroplasty was 0.1 (95% CI, 0.0-0.2 percentage points) to 6.9 percentage points (95% CI, 4.6-9.2 percentage points) higher among high- vs. low-income populations. With few exceptions, LOS, adjusted 30-day readmission rate, and time to surgery were shorter and lower for high-income patients.

conclusionsIncome-based disparities in treatments and outcomes for older adults hospitalized for hip fractures differed in magnitude, but were present in all six high-income countries. Defying our expectations, the USA did not have consistently larger disparities than other countries suggesting that the impacts of poverty exist in vastly different healthcare systems and transcend geopolitical borders.
