Age-related variations in clinical characteristics of patients with diabetic foot ulcers.

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
objectiveDiabetic foot ulcers (DFUs) have increasingly affected younger populations. This study aimed to analyze the clinical characteristics of DFUs in different age groups of diabetic patients with foot ulcers.
methodsThis is a retrospective cohort study of diabetic patients with foot ulcers admitted to West China Hospital, Sichuan University. They were divided into the young (<45 years), the middle-aged (45-64 years), and the elderly groups (≥65 years). The patients were followed up for a median of 44.5 months, either at the outpatient department or by phone.
resultsThis study enrolled 1,209 patients with DFUs, stratified into three groups according to age: young (n = 65), middle-aged (n = 509), and elderly (n = 635). All patients had a long history of diabetes with an average duration of 11.5 years. The DFU patients of all ages have poor glycemic control. About one-third of the patients have recurrent foot ulcers. The prevalence of comorbidities such as hypertension, coronary artery disease, chronic kidney disease, and peripheral artery disease increased significantly with age (P < 0.001). Neuropathic foot ulcers were more common in the young patients (48.3%), whereas neuro-ischemic ulcers were more prevalent in the middle-aged (42.1%) and elderly patients (56.9%). Compared with the young (27.7%) and middle-aged patients (26.9%), the ulcer healing rates during hospitalization were significantly lower in the elderly patients (18.9%, P = 0.004). During a median 44.5 (IQR 18.7-74.5)-month follow-up period, 375 (36.2%) deaths occurred, and all-cause mortality increased significantly with age (P < 0.001).
conclusionClinical characteristics of DFUs are profoundly age-dependent: younger patients exhibited poorer glycemic control, neuropathic ulcers, and mechanical injuries, while the older patients developed more vascular complications and neuro-ischemic ulcers. Therefore, different prevention and treatment measures should be taken for DFUs based on their clinical characteristics in different age groups.
