Enabling Fresh-Produce Availability in Long-Term Care via Hydroponic Green Walls: A Multisite Operational and Cost Evaluation.
Observational study in Nutrients, 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
BACKGROUND/
objectivesLimited access to fresh produce and persistent nutrition risk in long-term care (LTC) can affect dietary quality and rehabilitation capacity, particularly where seasonality and supply constraints affect food environments. Indoor hydroponic systems may support on-site production of leafy greens and herbs, but their adoption depends on practical feasibility. This study evaluated the routine staffing time and labour-only costs associated with maintaining hydroponic green wall units in LTC settings.
methodsA prospective, multi-site observational quantitative service evaluation was conducted from March 2023 to September 2024 across four LTC settings in Western Canada. Staff and volunteers logged routine interactions with wall-mounted hydroponic green wall units using adjacent mounted iPads. Entries captured task type(s), duration, using prespecified time categories, and staff role. Descriptive analyses summarized entries and actions by role and site. Labour costs were estimated using province-specific wage bands. Workload and costs were normalized using active weeks as weeks with ≥1 logged interaction.
resultsA total of 112 log entries were recorded, corresponding to 362 logged actions and 962.0 min of recorded staff engagement time. Recreation therapists/dietitians submitted 45.5% of entries (
conclusionsRoutine upkeep of hydroponic green wall units required modest, predictable staff time and low labour-only costs, with responsibilities largely distributed across non-registered nurse roles. These findings provide feasibility parameters relevant to sustaining hydroponics as an enabling infrastructure component of nutrition-supportive LTC food environments and may be of value to inform future outcome-focused evaluations incorporating production, utilization, nutrition and rehabilitation-relevant endpoints.
