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
The rapid electrification of transportation is generating a growing stream of retired electric vehicle batteries, creating challenges in battery waste management and the provision of affordable energy storage for renewable energy integration. Repurposing these batteries for stationary applications offers a circular-economy solution that addresses both issues. This study evaluates the techno-economic and environmental viability of integrating containerized second-life lithium-ion batteries (SLBs) into a grid-connected hybrid renewable energy system (HRES) for a residential community in Kuala Lumpur, Malaysia. Using HOMER Pro, four configurations incorporating either new or second-life batteries were compared. The results show that the HRES-4 configuration reduces grid dependency by more than 54%, transforms the system into a net energy exporter (>820 MWh/year), and achieves the best economic performance, with a net present cost of $239.6K and a levelized cost of storage of $0.072/kWh. Despite higher degradation rates, SLBs deliver energy throughput and cycling performance comparable to new batteries, exceeding 207 MWh/year and 230 equivalent full cycles annually. SLB integration also avoids approximately 1161 tons of CO
