The knowledge-perception nexus: socio-linguistic disparities in surgical informed consent among patients at Ethiopian tertiary hospitals.
Article in BMC surgery, 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
backgroundSurgical informed consent (SIC), the ethical bedrock of patient autonomy is undermined by profound sociodemographic disparities in resource-limited settings. This study aimed to evaluate the knowledge-perception nexus and sociolinguistic determinants of SIC comprehension among surgical patients in Ethiopian tertiary hospitals.
methodsThis institution-based cross-sectional study was conducted among 412 surgical patients in Addis Ababa tertiary hospitals between March 8 to April 30, 2023. The validated interviewer-administered questionnaire was used to assess knowledge and perceptions. Descriptive statistics were used to summarize participant characteristics, and multivariable logistic regression identified predictors (P < 0.05).
resultsOnly 52.2% demonstrated adequate SIC knowledge; 57.8% had positive perceptions. strongest knowledge predictors were higher education (AOR = 5.21, 95% CI: 3.12-8.68), prior surgery (AOR = 4.58, 95% CI: 2.87-7.32), male sex (AOR = 2.28, 95% CI: 1.52-3.42), and native-language proficiency (AOR = 1.83, 95% CI: 1.09-3.07). Favorable perception associated with urban residence (AOR = 3.99, 95% CI: 2.34-6.80) and marriage (AOR = 1.79, 95% CI: 1.16-2.78). Adequate knowledge independently predicted positive perception (AOR = 1.64, 95% CI: 1.02-2.62), explaining 68% of perception variance.
conclusionSurgical patients in Ethiopia demonstrated inadequate knowledge and perceptions of informed consent, influenced by gender, education, residence, and language barriers. The association between knowledge and perception highlights the need for culturally appropriate interventions, including teach-back methods and shared decision-making to improve informed consent practices and surgical care outcomes in resource-limited settings.
