Impact of delayed amputation on clinical outcomes compared to that of early amputation in patients with blunt polytrauma.
Article in Scientific reports, 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
Delayed amputation after failed limb salvage can lead to negative clinical and functional outcomes due to complications, including re-amputation. This study aimed to compare clinical outcomes and identify risk factors according to the timing of amputation. A retrospective review of lower-extremity injuries managed between January 2016 and December 2022 at a level 1 trauma center was conducted. Outcomes were compared between early amputation (within 48 h) and delayed amputation (beyond 48 h) groups. The primary outcome was the risk of a more proximal amputation level according to the timing of amputation. Secondary outcomes included trauma-related complications and clinical outcomes. Trauma-related complications were more common in the delayed amputation group, with no significant differences in 30-day mortality. Delayed amputation and deep surgical infection at the stump site were associated with higher odds of a more proximal amputation level than initially predicted. The overall hospital stay was significantly longer in the delayed amputation group. While there is no established standard for deciding between limb salvage and amputation strategies, delayed amputation could be a risk factor for shorter limb stumps owing to re-amputation, and patients may experience more trauma-related complications and prolonged hospitalization.
