Descriptive Analysis of Types and Diagnoses Associated with Lower Extremity Amputation: Analysis of the US Veterans Health Administration Database 2019-2023.

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
introductionVeterans in the US have higher rates of lower extremity amputation (LEA) compared to the general population and these rates have increased between 2008 and 2018. There is limited data which directly evaluate the potential underlying comorbidities associated with LEA in the veterans' population especially with the most recent data. Such information is critical to help inform clinical management strategies to reduce the risk of amputations among our veterans.
methodsThis was a retrospective observational study of adults in the Veterans Health Administration database who underwent LEA from January 1, 2019 to December 31, 2023. The date of the first LEA procedure was defined as the index date. Index LEA type, patient demographic at baseline, and clinical characteristics (including diagnoses for conditions associated with LEA and other comorbidities) 1 year before and 30 days after the index LEA procedure (except for bacterial infections which the identification period was 30 days before and 30 days after the index LEA procedure) were described.
resultsOf the 27,134 Veterans with LEA, 67.3% were ≥ 65 years of age, 97.0% were male, and 65.3% were non-Hispanic white. The most common type of LEA was transmetatarsal (52.9%), followed by toe (21.9%), above-knee (15.4%), and below-knee (9.8%). The most prevalent diagnoses associated with LEA were diabetes (81.6%), bacterial infections (79.1%), and peripheral artery disease (PAD; 63.3%). Only 15 Veterans (< 0.1%) had a diagnosis for combat-related injuries to lower extremities.
conclusionDiabetes and PAD are highly prevalent and among the main conditions associated with LEA among US Veterans. Earlier and more effective preventative and clinical management of these conditions offer an opportunity to significantly reduce the rates of LEA in this population.
