Distinct Health-Related Quality of Life Recovery Trajectories Among ICU Survivors: A Multicentre Prospective Cohort Study Using the EQ-5D-5L.
Observational study in Nursing in critical care, 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
backgroundICU survivors frequently experience reduced health-related quality of life (HRQoL); however, recovery trajectories vary considerably, underscoring the need to identify distinct subgroups for targeted follow-up.
aimsTo identify distinct HRQoL trajectory groups among ICU survivors, compare EQ-5D-5L profiles across groups and explore associated factors. STUDY
designThis multicentre prospective study included 19 ICUs in four South Korean university hospitals. Adult survivors with admissions ≥ 24 h were assessed using the EQ-5D-5L over 24 months post-discharge. Trajectory groups were identified via latent-class mixed modelling, and associated factors via multinomial logistic regression.
resultsAmong 609 survivors, three groups emerged: normative stable (58.3%), suboptimal (31.7%) and persistently low (10.0%). The normative stable group maintained HRQoL near the Korean population norm. The suboptimal group showed persistently reduced HRQoL, with moderate-to-extreme problems in mobility and pain/discomfort at 24 months. The persistently low group exhibited profound, sustained impairment, particularly in mobility, usual activities and pain/discomfort. Older age (aOR 1.72, 95% CI 1.07-2.75), lower educational attainment (aOR 2.11, 95% CI 1.34-3.32) and ICU delirium (aOR 2.14, 95% CI 1.10-4.15) were associated with suboptimal membership, whereas surgical admission showed lower odds (aOR 0.49, 95% CI 0.26-0.94). Multimorbidity (aOR 3.36, 95% CI 1.69-6.69) and discharge to an extended care facility (aOR 4.97, 95% CI 2.40-10.27) were associated with persistently low membership.
conclusionsThree distinct HRQoL recovery trajectories emerged over 24 months post-discharge. Although most survivors maintained near-normal HRQoL, unfavourable groups experienced sustained impairment in mobility and pain/discomfort. These findings support trajectory-based approaches for identifying high-risk phenotypes and guiding individualised post-ICU care. RELEVANCE TO CLINICAL PRACTICE: The persistent mobility and pain/discomfort problems highlight the importance of repeated assessment during post-ICU follow-up. Critical care nurses may consider them alongside ICU delirium history, multimorbidity and discharge destination; however, prospective validation is required before these trajectories or factors can identify high-risk survivors.
