AuLCA: augmented life cycle assessment for chemical data gaps.
Article in Green chemistry : an international journal and green chemistry resource : GC, 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
Life cycle assessment (LCA) has become the prevalent tool to quantify the impact of chemical processes, yet data gaps remain a major obstacle towards its widespread adoption. Existing LCA databases cover a few thousand, mostly high-production-volume, chemicals; however, fine chemicals are often underrepresented. Here we introduce an augmented LCA (AuLCA) framework based on chemical reaction networks (CRN), mass-based impact propagation, and first principles-based energy estimations to predict the life cycle inventories and impacts of chemicals. By applying AuLCA to four case studies, we find good agreement with commercial data, with the accuracy level depending on the chemical reaction network's size and density. Overall, AuLCA is intended to support sustainable decision-making across chemical scales, particularly in early-stage decisions on chemical reaction pathways selection.
