Rethinking Food Waste in Aged Care: A Systematic Review Framing Food Waste as an Ecosystem Issue.
Synthesis in Australasian journal on ageing, 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
objectivesTo synthesise evidence on food waste in Aged Residential Care (ARC) facilities, identify organisational, cultural and structural drivers, and develop a conceptual model to inform practice and research.
methodsFollowing PRISMA guidelines, five databases (1990-2025) were searched. Nineteen peer-reviewed studies met inclusion criteria. Narrative synthesis and inductive coding were used to identify barriers, facilitators and organisational responses, which were integrated into a conceptual model of the ARC food waste ecosystem.
resultsFood waste responses were largely fragmented and rarely embedded in strategy or policy. Barriers and facilitators commonly overlapped, including communication, training and infrastructure. Resident involvement was limited, and few studies evaluated intervention effectiveness or used theoretical framing.
conclusionsFood waste in ARC is an ecosystem issue shaped by interdependent organisational, staff, resident and policy factors. The model highlights leverage points for integrated, sustainable change linking waste reduction, staff capacity and resident wellbeing.
