Functional outcomes following injury in centenarians: a nationwide retrospective observational study.
Observational study in World journal of emergency surgery : WJES, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAdvances in healthcare and the development of various technologies have improved disease-free longevity. Although the number of healthy centenarians is gradually increasing, studies on postinjury functions among centenarians are lacking. Therefore, we aimed to determine the clinical predictors of mortality and unfavorable functions after injury among centenarians.
methodA retrospective study was conducted using a nationwide trauma database, and data from patients aged ≥ 100 years across ≥ 250 institutions during 2019-2022 were analyzed. Patient demographics, comorbidities, mechanism of injury, injury severity, vital signs on arrival, and pre- and in-hospital treatments were compared between survivors and non-survivors as well as between survivors who had and did not have the ability to live independently at discharge, which was defined as Glasgow Outcome Scale (GCS) score of ≤ 3. Independent predictors of in-hospital mortality and unfavorable functions after injury were examined using a generalized estimating equation model to account for institutional and regional differences in the management and characteristics of centenarians.
resultsOf the 409 centenarians, 384 (93.9%) survived to discharge. Although 208 (50.9%) patients had lived independently before the injury, only 91 (22.2%) could live independently at discharge. All patients had blunt injury, and fall from standing was the most frequent (86.6%) mechanism. The injury severity score was 10 ± 5, and surgery/angiography was performed in < 2% of the centenarians, except for fracture fixation in the extremity/pelvis, which was conducted in 225 (55.0%) patients. The adjusted model revealed three independent predictors of in-hospital mortality: male gender, mechanism of injury other than fall from standing, and GCS score on arrival. In contrast, only injury severity in the extremity/pelvis was an independent predictor of unfavorable functions after injury.
conclusionMale gender, mechanisms of injury other than fall from standing, and GCS on arrival were associated with higher in-hospital mortality. Injury severity in the extremity/pelvis was related to dependent living after injury among centenarians.
