Pre-discharge energy intake and post-discharge mortality in acutely hospitalized older adults.
Article in Aging clinical and experimental research, 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
backgroundUndernutrition is a prevalent issue among hospitalized older adults. Dietary intake is a major factor in nutritional status. Although insufficient dietary intake during hospitalization has been well documented, little research has focused on dietary intake at discharge, which may reflect the patient's true dietary intake capacity. Furthermore, it would be desirable for energy intake to be estimated in a clinically feasible way.
objectiveThis study aimed to assess pre-discharge energy intake using routinely recorded dietary intake data, and to examine the association between pre-discharge energy intake and post-discharge mortality in older inpatients.
methodsA prospective cohort study was conducted in a geriatric ward. Energy intake in the 3 days prior to discharge was estimated using visually assessed dietary intake data recorded in medical records. The primary outcome was 3-month post-discharge mortality.
resultsA total of 257 patients (mean age 84.7 years) was included. The mean pre-discharge energy intake was 1327 ± 315 kcal/day, with 74.7% of patients failing to meet recommended energy intake levels. Within 3 months post-discharge, 18 patients (7.0%) had died. Cox regression analysis revealed that higher pre-discharge energy intake was associated with lower post-discharge mortality (per 100 kcal/day, hazard ratio 0.75, 95% confidence interval 0.65-0.86), independent of other prognostic factors such as comorbidities and functional status.
conclusionMany patients did not reach their recommended energy intake at discharge. Integrating routine monitoring of pre-discharge energy intake into discharge planning could trigger timely nutritional interventions and goal-of-care discussions, thereby improving post-discharge outcomes.
