Psychometric properties of the Chinese version of the Subarachnoid Hemorrhage Outcomes Tool (SAHOT) in elderly SAH patients.
Article in BMC geriatrics, 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
backgroundElderly patients with subarachnoid hemorrhage (SAH) experience long-term disability and persistent cognitive and psychosocial sequelae, with poor patient-reported outcomes (PROs). However, China currently lacks tools to assess PROs in elderly SAH patients. This study aims to translate the Subarachnoid Hemorrhage Outcomes Tool (SAHOT) into Chinese and evaluate its psychometric properties among elderly SAH patients in China.
methodA cross-sectional study involving 404 elderly patients with subarachnoid hemorrhage (SAH) was conducted. The original scale was translated into Chinese using the Brislin translation technique. The reliability of the Chinese version of the SAHOT was assessed through internal consistency and split-half reliability. Its validity was evaluated using content validity, convergent validity, and criterion validity.
resultThe Chinese version of the SAHOT (C-SAHOT) comprises 4 dimensions and 56 items, demonstrating excellent internal consistency (Cronbach’s α = 0.964) and split-half reliability (0.761). The content validity index at the scale level is 1.0; AVE values for each dimension ranged from 0.592 to 0.627, while CR values ranged from 0.943 to 0.964. The C-SAHOT showed a significant negative correlation with scores on the Short Form Stroke Quality of Life Scale (r = -0.674, P < 0.001). Exploratory factor analysis revealed a four-factor structure explaining 64.730% of total variance.
conclusionThe Chinese version of SAHOT demonstrates good reliability and validity among elderly SAH patients in China. It effectively measures the PROs levels of these patients, providing a basis for their PROs management.
