Research Ethics Committees (RECs) perspectives on large language models and AI ethics review: a South African case.
Article in BMC medical ethics, 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
backgroundThe rapid integration of Large Language Models (LLMs) into health research presents a dual promise: to serve as an epistemic equalizer by lowering barriers to scientific participation, and a significant governance challenge, risking a "validity gap" where output volume outpaces integrity. Research Ethics Committees (RECs), tasked with safeguarding research, face a critical "purview weakness" in evaluating these opaque technologies. This tension is most acute in African contexts, where the need for innovation intersects with vulnerability to algorithmic colonization and where empirical data on REC preparedness is absent.
methodsA qualitative study employing in-depth, semi-structured interviews was conducted with a purposively sampled cohort of 14 REC chairs, members, and research ethics office staff from health science institutions across South Africa. Data were collected between January and July 2024, transcribed verbatim, and analysed using inductive thematic analysis.
resultsAnalysis yielded five central themes namely: (1) understanding of LLMs, (2) perceived benefits of LLMs use in health research, (3) perceived challenges and concerns in the use of LLMs in health research, (4) human oversight - augmentation, not automation, and (5) fragmented AI literacy within the research. Respondents recognized significant benefits in administrative efficiency, research lifecycle support, and democratizing writing skills. Crucially, there was unanimous consensus that LLMs must only augment, not automate, ethics review. Human oversight was deemed irreplaceable for contextual understanding, empathy, and complex moral deliberation qualities respondents implicitly aligned with relational, Ubuntu-informed ethics.
conclusionSouth African ethics gatekeepers perceive LLMs as powerful but risky tools. Their insistence on human-centric governance, rooted in contextual and communal values, provides a vital counter-narrative to purely technocratic oversight models. These findings provide an urgent empirical foundation for developing context-specific AI governance guidelines in African and other LMIC health research systems.
