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

backgroundTo determine the influence of obesity on short-term outcomes in patients with blunt liver trauma.

methodsThe US Nationwide Inpatient Sample (NIS) database 2005-2020 was reviewed to identify patients ≥ 18 years old with blunt liver trauma. Patients were categorized based on body mass index (BMI) into morbidly obese (BMI > 40 kg/m

resultsA total of 4121 patients were included, representing an estimated 20,382 patients nationwide. The mean age was 46.4 years, and 51.0% were male. Both obese and morbidly obese patients had significantly increased risks of in-hospital mortality (obese: adjusted odds ratio [aOR] = 1.59, 95% confidence interval [CI] 1.05-2.14; morbidly obese: aOR = 2.43, 95% CI 1.61-3.65). Morbid obesity was associated with increased risks of acute kidney injury (AKI) (aOR = 1.90, 95% CI 1.50-2.41) and shock (aOR = 1.56, 95% CI 1.21-2.01). However, patients with non-morbid obesity had significantly lower risks of prolonged LOS (aOR = 0.61, 95% CI 0.50-0.75), non-routine discharge (aOR = 0.66, 95% CI 0.53-0.81), and complications (aOR = 0.69, 95% CI: 0.57-0.83) compared to non-obese individuals.

conclusionPatients with morbid obesity who sustain blunt liver trauma are at increased risk of in-hospital mortality, AKI, and shock compared to non-obese individuals. Despite higher mortality risk, non-morbid obese patients have a lower risk of prolonged LOS, non-routine discharges, and complications.
