Separation of Volatile Fatty Acids by Simulated Moving Bed.
Article in Industrial & engineering chemistry research, 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
This work evaluated the feasibility of the simulated moving bed (SMB) technology to fractionate volatile fatty acids produced through wastewater acidogenic fermentation. A lab-scale SMB unit equipped with 6 columns (FlexSMB), each packed with a nonfunctionalized resin (Amberlite XAD-4), was used to separate a binary solution of acetic and propanoic acids, for proof of concept. SMB operating conditions were first determined by building the separation region for a limit purity of 95% in both extract and raffinate streams, and a 1-2-2-1 column configuration. The process accomplished the separation of acetic and propanoic acids in the raffinate and extract streams, with purities of 97.8% and 100.0%, and recoveries of 100.0% and 97.8%, respectively. Productivities reached 2.93 and 2.81 mmol·g
