Caregiver burden and in-hospital mortality in older adults: insights from a Mexican single-center Latin American study.
Observational study in European geriatric medicine, 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
purposeTo evaluate the relationship between caregiver burden and in-hospital mortality in older adults.
methodsA prospective observational cohort including 252 adults aged ≥ 65 years hospitalized at the Hospital General de Zona No. 2 (Saltillo, Mexico) from May to July 2025. Caregiver burden was assessed at admission using the Spanish-validated 22-item Zarit Burden Interview. Patients were followed until discharge or death to determine in-hospital mortality.
resultsA total of 252 patients were included, with a mean age of 74.6 ± 7.3 years; 56.7% were women. Overall mortality was 22.6%. Mortality by burden was none-10.4% (20/192), mild-48.6% (18/37), severe-82.6% (19/23); p < 0.001. After adjustment, mild burden had RR = 4.23 (95% CI 2.47-7.21; p < 0.001), severe burden RR = 5.88 (95% CI 3.58-9.67; p < 0.001). Each additional year of age increased mortality risk by 3.5% (RR = 1.035; 95% CI 1.012-1.058; p = 0.003).
conclusionsCaregiver burden was independently associated with increased in-hospital mortality. Systematic caregiver assessment should be considered in geriatric practice.
