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
purposeThis study examined the direct and indirect associations among health literacy (HL), its determinants, and health-related quality of life (HRQoL) in individuals with physical disabilities based on the Integrated Model of Health Literacy (IMHL).
methodsThis cross-sectional study analyzed data from 441 adults with physical disabilities obtained from the 2021 Korea Health Panel Survey. Based on the IMHL, path analysis was conducted to examine the direct and indirect associations of situational determinants (usual source of care, need for care) and societal and environmental determinants (employment status, unmet healthcare needs) on HL and HRQoL.
resultsAmong the participants, 44.0% were classified as having inadequate HL and 22.3% as problematic. Need for care was negatively associated with both HL (β = - 0.12, p = .002) and HRQoL (β = - 0.33, p < .001). Unmet healthcare needs also had a significant negative direct association with HRQoL (β = - 0.17, p < .001). Employment status (β = 0.15, p < .001) and HL (β = 0.13, p = .005) were positively associated with HRQoL. HL partially mediated the relationship between need for care and HRQoL (β = - 0.02, p = .044).
conclusionThese findings highlight the role of HL in relation to HRQoL among individuals with physical disabilities. Improving HRQoL in this population may require approaches that go beyond individual-level HL promotion and also address support for care-dependent individuals and structural factors, including healthcare accessibility and employment opportunities.
