Permanent cognitive or physical impairment after transfer from long-term care to acute care: a retrospective cohort study.
Article in Age and ageing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLong-term care (LTC) residents are frequently transferred to emergency departments (ED), which may increase the risk of impairment.
objectiveTo examine associations between all-cause ED transfers and development of new permanent severe physical and cognitive impairments, and death. SETTING AND PARTICIPANT: Adults ≥65 with incident admission to LTC homes in Ontario, Canada between 2013 and 2018.
methodsWe conducted a retrospective cohort study. We examined rates of (i) severe physical impairment, (ii) severe cognitive impairment and (iii) all-cause mortality after transfer to ED. We used marginal structural models to estimate the combined effect of acute illness and ED transfer. We used an instrumental variable (IV) analysis to isolate the effect of transfer, adjusting for acute illness.
resultsOf 120,238 residents, 78,546 (65.3%) residents had at least one transfer to the hospital. The mean (SD) age was 84.6 (7.9) years, 67.2% were female. The incidence rate ratios were 3.0 (95% CI, 2.9-3.1) for new physical impairment, 2.2 (95% CI, 2.1-2.3) for cognitive impairment and 5.8 (95% CI, 5.7-5.9) for mortality, comparing transferred to never-transferred residents. In IV analysis, transfers were not associated with permanent physical or cognitive impairment (hazard ratio [HR] (95% CI) [HR1.20] (0.92-1.55); [HR0.86] (0.69-1.06), but were associated with decreased mortality [HR0.57] (CI 0.50-0.63).
conclusionIn unadjusted analyses, residents transferred to ED had a higher incidence of permanent physical impairment, cognitive impairment and mortality. After adjusting for acute illness, transfer decisions were not associated with changes in the risk of severe impairment and were associated with reduced mortality.
