Relatively upstream factors associated with pressure injury occurrence and staging in older hospitalized patients: a prospective observational study.
Observational study in BMC geriatrics, 2026. 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
backgroundThe Braden Scale is widely used to assess the direct physiological risks of pressure injuries. However, there is limited research on the relatively upstream risk factors for the parameters assessed by the Braden Scale, such as pre-admission living environment, education, and chronic disease history, as well as proximal factors such as, incontinence and mobility.
methodsThis prospective observational study enrolled 86 older patients. Patient age, education, pre-admission living environment, diet, hypertension, diabetes, urinary and bowel function, relationship between caregivers and patients during hospitalization, and functional mobility were analyzed. Risk factor analysis and screening were conducted using a chi-square test or Fisher's exact test. The relationship between risk factors and pressure injury staging was analyzed using unconditional logistic regression.
resultsUnivariate analysis indicated that the risk factors for pressure injury in older patients during hospitalization included the patient's living environment before admission (P = 0.032), urinary and fecal incontinence (P = 0.004), and mobility (P = 0.008). Further unconditional logistic regression results indicated that urinary and fecal incontinence were also associated with pressure injury staging.
conclusionIn this observational study, urinary and fecal incontinence were associated with both the occurrence and severity of pressure injuries in older hospitalized patients, whereas associations with pre-admission living environment and mobility were not sustained after adjustment. These exploratory findings suggest that graded continence assessment and care may be a worthwhile focus for future interventional research.
