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
objectiveTo identify distinct long-term functional recovery trajectories among intensive care unit (ICU)-treated patients with spontaneous intracerebral hemorrhage (ICH) and to evaluate whether trajectory-based classification improves prediction of long-term quality of life (QoL) compared with conventional single time-point functional assessment.
methodsWe conducted a prospective longitudinal cohort study of consecutive adult patients with spontaneous ICH admitted to a tertiary ICU between January 2024 and January 2025. Survivors to hospital discharge were followed for 12 months. Functional status was assessed using the modified Rankin Scale (mRS) at hospital discharge, 90 days, 6 months, and 12 months. Latent class mixed modeling (LCMM) was used to identify distinct recovery trajectories. Health-related QoL at 12 months was measured using the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) instrument. Multinomial logistic regression was performed to evaluate associations between early clinical characteristics and trajectory membership. Receiver operating characteristic curve analysis was conducted to compare the predictive performance of trajectory membership and 90-day mRS for 12-month QoL.
resultsAmong 196 patients (mean age 61.7 ± 12.4 years; 60.2% male), three distinct functional recovery trajectories were identified: good, moderate, and poor recovery. Twelve-month QoL demonstrated a graded decline across trajectory groups. Older age, lower admission Glasgow Coma Scale scores, and larger hematoma volume were independently associated with both moderate and poor recovery trajectories, while intraventricular hemorrhage, mechanical ventilation, and prolonged sedation (>48 hours) were specifically associated with the poor recovery trajectory. Trajectory-based classification demonstrated superior predictive performance for 12-month QoL compared with 90-day mRS (area under the curve [AUC], 0.81 vs 0.72;
conclusionICU-treated patients with intracerebral hemorrhage exhibit distinct long-term recovery trajectories that are strongly associated with quality of life. Importantly, trajectory-based classification provides incremental prognostic value beyond conventional single time-point functional assessment, supporting a shift toward dynamic outcome modeling for long-term prognostication in ICH.
